Inconsistent curb idle and low power at RPMs

LETS MOVE THE VACUUM ADVANCE HOSE --- TO A PORT JUST ABOVE THE THROTTLE PLATES. IT WILL NOW BE ON PORTED VACUUM

READJUST YOUR IDLE SPEED BACK TO 680 RPM ONCE YOU MOVE THE HOSE

THEN SEE IF THE 'LIL MEXICAN GAL STOPS WITH THE CASTANETS

LET ME KNOW THE RESULTS---NEXT STEP IS, I WILL EXPLAIN HOW TO CHECK BOTH ADVANCES WITH A TIMING LIGHT, TO INSURE THEY WORK AS THEY SHOULD

THE MEDIC

1-3 CJ-10 DIESEL

4-5 (MY)"WILLY"

BETTER GAS MAY HELP

SOUNDS LIKE YOU STILL HAVE A VACUUM LEAK SOMEWHERE

MIX SCREWS WAY OUT MEANS IT IS TAKING MORE FUEL TO MIX WITH THE "EXTRA AIR" THAT YOU SHOULD NOT HAVE AT IDLE

CHECK THE INTAKE MANIFOLD BOLTS AND GASKET AND THE CARB TO INTAKE NUTS

THE PORT ON THE SIDE OF THE INTAKE MANIFOLD AND A PIECE OF 3 FOOT HOSE MAY AID IN THIS POSSIBILITY OF FINDING A LEAK....THIS MIGHT WORK FOR YOU---HAVE A HELPER AID YOU IN THE SEARCH OR WITH THE SMOKIE!---SEAL THE CARB THROAT WITH TAPE

GOOD HUNTIN'!

THE MEDIC

LET'S USE A FLASHLIGHT. NOT A CIGARETTE LIGHTER!

LOOK DOWN INTO THE CARB THROAT

THEN PULL BACK ON THE THROTTLE

ARE WE SEEING 2 REALLY NICE SQUIRTS (STREAMS) OF FUEL FROM THE ACCELERATOR PUMP? THEY SHOULD LOOK LIKE MINIATURE SQUIRT GUNS STREAMS. NOT A MIST AND NOT A DRIBBLE

THIS IS WHAT GIVES THE ENGINE A "KICK" WHEN YOU ACCELERATE, UNTIL THE VACUUM ACTION STARTS DRAWING FUEL FROM THE VENTURIES

THE PUMP ITSELF IS A TOY DART GUN DART. SUCTION CUP DEVICE INSIDE THE CARB.

IT MAY BE "SHOT" --- IT MAY BE OUT OF ADJUSTMENT -- YOU MAY HAVE ACCIDENTALLY DISCONNECTED IT FROM IT'S ACTUATOR

SOME OF THE PROCEDURES FOR IT CAN BE DONE BY REMOVING THE LID UP WHERE THE BOWL VENT IS. WITHOUT TEARING INTO IT

THERE ARE 2 PLASTIC CAMS IN THERE AS WELL AS THE METERING RODS. SPECIAL CARE MUST BE TAKEN WHEN TIGHTENING THE SCREWSYOU MUST HOLD DOWN ON THE CENTER OF THE METERING RODS TO KEEP THEM "IN THEIR CAMMED POSITION" AND NOT TO LET THEM JUMP OUT.

IF THEY DO JUMP OUT. THERE IS A HAIR LIKE SPRING THAT HOOKS TO EACH ROD---THEY MUST GO BACK INTO THEIR "HOLES" FREELY AND MOVE FREELY--THE ASSEMBLY MUST BE CAPTURED IN THE PLASTIC CAM-LIKE ADJUSTMENT. REALLY LOOK AT THIS STUFF AS YOU TAKE IT LOOSE. NOTHING SHOULD BIND, NOT EVEN A LITTLE BIT WHEN YOU ACTUATE THE THROTTLE GENTLY.I'VE SEEN THE METERING RODS BROKEN AND BENT OVER THE YEARS

BOTH THE ACCELERATOR PUMP AND THE METERING RODS MUST BE ADJUSTED CORRECTLY (SEE CHARTS). THEY ARE SEPARATE ASSEMBLIES THAT OPERATE OFF OF THE SAME AXLE/ OR ACTUATING ROD

"THE KNOWLEDGE BASE" SHOULD SHOW AND EXPLAIN THINGS WELL. ONE OTHER ADJUSTMENT IS A GAP ADJUSTMENT USING AN ALLEN SCREW ON TOP---USUALLY NO ONE MONKEYS WITH IT, LOOK AT IT WHILE YOU ARE IN THERE.

THE METERING RODS ARE VERY IMPORTANT IN LETTING THE CORRECT AMOUNT OF FUEL ENTER THE VENTURIES AT DIFFERENT THROTTLE POSITIONS AS THEY "OPEN" OR "BLOCK OFF" THE PASSAGE WAYS. THIS GIVES THE PROPER FUEL TO BE MIXED WITH THE PROPER AIR COMING DOWN THE THROAT. HENCE AIR/ FUEL RATIO, PERFECTION BEING AS CLOSE TO 14.7/1

THAT'S 14.7/1 (AIR/ FUEL) AT ---IDLE---ANY THROTTLE POSITION.

A NEW COMPUTER VEHICLE W/ INJECTORS CAN KEEP THIS RATIO CLOSE AND CONSISTENT

A CARB CAN'T COMPENSATE (WITHOUT A COMPUTER AND INJECTORS) TO KEEP EFFICIENCY HIGH. THE CARB AND OTHER SYSTEMS WERE DESIGNED TO BE REALLY EFFICIENT FOR "THEIR DAY", AS LONG AS THINGS ARE ADJUSTED A PERFECTLY AS POSSIBLE AND THE SYSTEMS ARE "IN SYNC"

I HAVE TRIED ALMOST ALL OF THE "GIMMICKS", FROM OPPOSING MAGNETS ON MY FUEL LINE--TO--THE OLE "TORNADO"

I BECAME OBSESSED WITH "MPGs"

I DID NOT CARE HOW MUCH THE COST WAS. EVEN IF MY "SAVINGS" NEVER WOULD "OFFSET" MY "GAIN"

.I HAD TO HAVE THE BRAGGING RIGHTS OF "I GET THIS MANY MPGs WITH MY 258 CJ 5!"

ON ONE OCCASION, I WAS ABLE TO SQUEEZE 16.7 MPG OUT OF A '79 BBD.W/ NO GIMMICKS. CONSISTENT 16 OR SO, WAS NOT UNCOMMON

THE "WEBER DGEV" PROMISED "UP TO" 20% MORE. IT WAS EZ TO JET AND CHANGE STUFF.I RECKON I JUST COULD'NT FIGURE OUT THE COMBINATION TO GET IT RIGHT. EVEN THOUGH I BOUGHT LOTS OF JETS AND OTHER GOODIES

ENTER "HOLLEY 390"

I GET ABOUT 18 MPG W/ MY HOLLEY, WHEN I DRIVE "NORMAL". THE O2 SENSOR AND AIR/FUEL RATIO GAUGE I INSTALLED AT THE SAME TIME AS THIS CARB, MADE JETTING EZer TO FIGURE OUT THAN THE WAYS I HAD TRIED WITH THE WEBER (HECK, LOOKING BACK, IF I HAD USED THE AIR/FUEL GAUGE W/ THE WEBER, IT MAY HAVE WORKED OUT A LOT BETTER)

ALTHOUGH I HAVE GOTTEN WHAT I WISHED FOR. YET

HERE'S MY "BRAG"---I GET 18 MPG! (NORMALLY)---I WAS ABLE TO "JET" REALLY FAST USING THE O2 METHOD

DOING THIS WITH A BBD IS PROBABLY NEARLY IMPOSSIBLE AS YOU MUST DISASSEMBLE THE WHOLE THING TO GET TO THE JETS AND AVAILABILITY OF METERING RODS AND JETS (WEBER AND HOLLEY, BASICALLY HAVE ACCESSES TO GET IN THERE)

I'M NO CARB MAN AS FAR AS THE "ENGINEERING END"---I STILL LEARN ALL THE TIME MYSELF

WONDERFUL!

I'D STILL TIME IT WITH THE LIGHT---I THINK WE WENT OVER THE WHOLE DEAL. DON'T FORGET TO REMOVE AND PLUG THE VACUUM ADVANCE AND BE AT THE RIGHT IDLE SPEED. THEN RECONNECT THE LINE WHEN YOU ARE DONE!

CONTINUE TO WAVE AT THE OTHER "REAL JEEPS". AND THE WRANGLERS TOO. WAVING AT THE "STATION WAGON MODELS" IS OPTIONAL (THEY MAY BE DECEIVING--MANY ARE ONLY 2WD)

WANT ME AGAIN? COME BACK TO THIS POST AND KEEP ADDINGI MAY NOT SEE YOU IF YOU START A WHOLE NEW QUESTION

UPDATE ME FROM TIME TO TIME. PICS ARE NICE TOO!

THE MEDIC

MAKE ME A LIST OFF ALL YOU WANT

DON'T BUY NUTHIN' YET. LET ME SHOW YOU THE $$$ SAVING TECHNIQUE

GIVEN?---SHOES / HARDWARE (SPRINGS--SELF ADJUSTERS--ETC)/ PADS/ L CALIPER/ R CALIPER/L WHEEL CYLINDER/ R WHEEL CYLINDER/ MASTER CYLINDER/ 2 LARGE CONTAINERS OF DOT 4 BRAKE FLUID

POSSIBLE NEW DRUMS AND ROTORS. ARE YOURS TURNABLE?

LIST ANYTHING ELSE YOU MIGHT NEED---SUBTRACT WHAT YOU DON'T NEED

ALL THE ABOVE ARE ITEMS (THIS IS EVERYTHING I CAN THINK OF---FOR BOTH SIDES)

THE TOTAL RIGHT NOW IS.$344.66

IF YOU DROP STUFF LIKE THE DRUMS AND ROTORS IT WILL BE LESS

AS IT STANDS NOW. WE MAY CAN SAVE $40 PER HUNDRED. THAT'S $120 KNOCKED OFF OF THE $344

WANNA KNOW MORE. MAYBE I ALREADY HAVE? (I DID SORTA SKIM THRU YOUR POST AND DID NOT SEE IT)

GET YOUR LIST TOGETHER. REPORT BACK. WE'LL MAKE THE CHANGES AND GO FROM THERE!

RIGHT NOW, I HAVE ALL OF YOUR ITEMS IN A SHOPPING CART.I PICKED OUT DECENT PARTS (NOT NECESSARILY THE MOST EXPENSIVE)

WAITIN' ON YOU

THE MEDIC

TIME FOR YOU TO DO SOME ADDING/ ARRANGING

THE IDEA (WITH NEW DRUMS) IS TO ARRANGE THIS INTO 3 SEPARATE ORDERS--BARELY OVER $100 EACH....IF A FOURTH ONE IS NEEDED, SO BE IT...WE'LL (YOU'LL) SAVE ON IT TOO!

I THINK THE DRUMS ARE COUPLED TOGETHER AS 1 ITEM....SPLIT THEM UP IF YOU NEED TO, TO GET THE ORDERS "JUST OVER" THE $100 MARK

IN ORDER DO GET IT ALL ON HERE...I MADE 4 "SCREEN SHOTS" EVERYTHING THAT SHOULD SHOW, DOES SHOW IN THE SHOTS

THIS IS FROM ADVANCE AUTO----"FABU" IS STILL THE PERFECT PROMO TO DO THIS...YOU GOTTA USE IT FOR EACH ORDER!

OK---HERE'S HOW IT WORKS.....SEE MY 7th AND 8th ANSWER IN THIS POST

http://www.2carpros.com/questions/1977-jeep-cj7-front-wheel-wont-into-4-low

I HAVE DONE THIS 3 TIMES IN THE LAST 3 WEEKS MYSELF---4 OTHER FRIEND DID IT TOO----ALONG WITH SEVERAL OTHER PEOPLE I TOLD AT THE STORE.....I HAVE SAVED $120 ALTOGETHER.......THE CODE DOES NOT WORK ON OIL PRODUCTS

NOW GET TO WORK---LET ME KNOW WHAT YOU COME UP WITH

TH LAST SHOT REFLECTS "REGULAR PRICE" IF EVERYTHING WAS BOUGHT IN ONE ORDER

THE MEDIC

CHRISTMAS WAS GOOD

DID NOT GET A BUNCH OF TOYS. DESPERATELY LOOKING FOR ANOTHER SERVICE ORIENTED PLUMBER TO WORK UNDER. I'M JUST NOT READY TO GO OUT ON MY OWN, I THINK THE HEADACHES MIGHT OUTWEIGH THE BENEFITS. BESIDES I HAVEN'T GOT ENOUGH CAPITAL UP TO START UP. THIS PART TIME AUTO PART JOB HELPS WITH SOME "NEW VEHICLE LEARNOLOGY". BARELY GETTING A LITTLE OVER MINIMUM WAGE IS FOR THE BIRDS. WIFE WANTS ME TO TAKE ON ANYTHING--NO MATTER WHAT."MEAT CUTTER" WAS THE LAST ONE SHE WANTED ME TO PURSUE. NOT ONLY WOULD BEING IN THE COLD MUFF ME UP (MINUS 5 DEGREES DURING RANGER SCHOOL BROKE ME FROM COLD ENVIRONMENTS) I WEAR LONG SLEEVES, MOST OF THE TIME, EVEN IN THE SUMMER---YOU WILL FIND NO LESS THAN TWO JACKETS AND/ OR COATS AND BLANKETS IN MY VEHICLES.I DON'T THINK I COULD KEEP MY HANDS "GREASE AND DIRT FREE" ENOUGH TO HAVE A JOB LIKE THAT.I NEED A MECHANICAL JOB IF I CANNOT FIND A JOB DOING WHAT I HAVE BEEN SCHOOL TRAINED FOR, I'VE BEEN PLUMBING SINCE 1989.

WE HAD THE--- "WHICH WAY DO THE BEARINGS GO" -- DISCUSSION BEFORE----I LOOKED BACK THRU THE POST.I THINK I SCANNED AND SENT YOU THE "MOSIER" (sp) INSTRUCTION SHEET FOR THE ONES I STILL HAVE IN THE BOX, ALONG WITH ALL NEW SEALS, AND AN EXTRA SET OF BEARINGS (BOUGHT LONG AGO [MAYBE 1994], NEVER INSTALLED)---THE AXLES ALONE WERE ABOUT $500

.I SENT IT TO YOU VIA EMAIL?

I COULD POSSIBLY STILL "SPIN" A HUB

IT'S ABOUT TIME FOR ONE OF MY REAR BEARINGS TO SHELL OUT

AMAZING HOW I HAVE DRIVEN THIS JEEP SINCE 1992--NEARLY EVERYDAY---MILES UNKNOWN---2 ENGINES---2 TRANNY REBUILDS--1 TRANSFER CASE REBUILD. THIS REAR END. AXLES. AND BEARINGS HAVE NOT BEEN TOUCHED

WHEN IT NEEDS THE BEARINGSIT WILL GET THE NEW ONE-PIECE AXLES!

AT THE SAME TIME I MIGHT DO THE DIFF. JUST FOR GIGGLES!

SO. DO YOU HAVE THE CORRECT INSTRUCTION SHEET FOR THE CROWN ONE-PIECE AXLES?

I'D MUCH RATHER HAVE THE "REAL INSTRUCTIONS" RATHER THAN "FREDDIE FREE-LOADER'S" OVER THE PHONE INSTRUCTIONS. AS HE TEXT--ES TO HIS NEWLY FOUND BAR HOPPIN' BABE THAT HE MET AT THE WATERING HOLE LAST NIGHT ON HIS GLOBAL SPACE STATION READY CELL PHONE

. MAYBE THAT'S WHAT HAPPENED LAST TIME WITH THE INFERIOR CELL PHONE HE DID HAVE?

I SEARCHED YOU TUBE FOR ABOUT 30 MINUTES PRIOR TO REPLYING----COULD NOT FIND INFO ON THE AXLES

I MAY TRY "GOOGLING" TO SEE IF I CAN HELP YOU WITH THE CORRECT WAY

YOUR REAR SEEMS TO BE IN SUPER SHAPE. OTHER THAN THE AXLES. MINE WOULD FIT PERFECTLY!

. SHOULD THE WHOLE REAR TURN UP MISSING.I HAVEN'T SEEN IT!

KEEP ME POSTED FREQUENTLY WHILE HE IS SICK.I CAN'T BEAR TO KNOW ONE OF 'EM IS NOT ROAD WORTHY. TELL ME WHAT I NEED TO DO.

THE MEDIC

THE 1ST SET I EVER BOUGHT---FROM?????----BACK IN ABOUT '85?

HAD ONE PIECE ROLLER BEARINGS, NOT TAPERED ONES......I NEVER HAD A PROBLEM, THIS WAS BEFORE "THE NET", SOLD THAT JEEP A FEW YEARS LATER........HEARD THRU THE GRAPEVINE, OTHERS (NOT THE JEEP I HAD PREVIOUSLY) HAD LOST THE REAR WHEEL AND AXLE, WHEN THE ROLLERS SHELLED OUT.........LOOKS LIKE IT WOULDA MADE A HECK OF A RACKET, LONG BEFORE IT COME OUT........SOME PEOPLE DON'T CARE, DRIVE IT ANYWAY, DESPITE OF THE "SCREAMS FOR HELP" GENERATING FROM THE REAR

THIS COULD BE THE REASON THE DESIGN IS NOW USING TAPERED BEARINGS

I'M NOT "MR. ON TOP OF EVERYTHING"---I'M NOT FACTORY TRAINED OR NONE OF THAT GOOD STUFF!......I TRY TO HELP ALL I CAN THRU MY OWN EXPERIENCES....I DO ATTEMPT TO LEARN ALL I CAN, USUALLY FROM NECESSITY, OR EVEN WHILE AIDING SOMEONE ELSE......NOT FROM SEARCHING ALL OVER AND SOAKING IT IN, LIKE IT WAS A HOBBY!.....................I DON'T RECKON MANY CAN SAY THEY HAVE HAD A CJ FOR A PRIMARY DRIVER.....THEIR WHOLE LIFE!

BEAR WITH ME ON SOME OF THIS STUFF

THE "MOSER" SET I STILL HAVE IN THE BOX, HAS TAPERED BEARINGS AND PRESS ON COLLARS.....THEY ARE AT MY M.OTHER'S HOUSE, IN MY STORAGE BUILDING....I'D PROBABLY HAVE TO LOOK AT 'EM TO SEE HOW THE BEARINGS GET PRELOADED (AS YOU KNOW WITH THE DIFF, CORRECT PRELOAD IS IMPORTANT)

TO SAVE ME A SEARCH (I RECKON YOU COULD CALL ME A EMAIL HOARDER, IN MY INBOX)--GO TO "MESSAGES" AND GIMME YOUR EMAIL AGAIN

NOW---ACTUALLY LUBING THE BEARINGS (ALL WHEEL BEARINGS AND ANY OTHER ONES THAT REQUIRE GREASE)----ALL BUT 90 WEIGHT LUBRICATED ONES (INTERNAL TRANNY/ TRANSFER CASE/ DIFF ARE EXCLUDED)
