Nikki carb floods, running rich

make sure the needle valve and seat are tight in the body. did you blow out all the vents?? did you soak it in carb cleaner?? is the float copper or plastic and did you replace it??

Roy

Hey great, thanks for the quick response. rebuilt the carb a few years back, most recently had it off completely once and have taken the top off more times than I can count to blow out all the ports and such, has plastic float which I recently put the old one I had from the rebuild back on, same with the float needle. Pulled out the air mix screw and blew that out as well with carb cleaner. The only lead I have right now is that perhaps the fuel pressure could be too high, dont have a way to test it...

THIS WORKS FOR ME.....SEE MY PICS

IT WAS ABOUT $12 FOR THE GAUGE--THE REGULATOR WAS MAYBE....$20

THIS IS ON MY '77 JEEP CJ 5 258 CID STRAIGHT 6 W/ A HOLLEY 390 4 BBL ON IT....OTHER IS A '46 WILLYS

MY PICS WERE INTENDED TO AID THE CJer IN GETTING STUFF BACK CORRECT---WHOSE JEEP HAS BEEN RIGGED OVER THE PAST YEARS 26-36 YEARS. SOMETIMES DUMMIES START BY ELIMINATING THE RETURN TO THE TANK (MAYBE BECAUSE A "IN AND OUT" FILTER IS CHEAPER?)....THE ORIGINAL SET-UP RELIEVES TOO MUCH PRESSURE GOING TO THE CARB

I'M MOSTLY IN TUNE WITH THE CJs, I HAVE ANSWERED MOST SINCE JAN 2010 HERE AT 2CAR...I'VE MADE LOTS OF PICS

MAYBE YOU NEED A CJ?

I ANSWERED YOU SINCE I HAVE SOME BASIC CARB EXPERIENCE

DOES YOUR FLOAT HAVE FUEL INSIDE OF IT?

THE PRESSURE GOING IN SHOULD BE THE 1ST THING YOU CHECK

NEED MORE INFO?--LET ME KNOW

Hey there. Looks like I got it, replying to this post for anyone who ends up having this same problem. Turns out it was what is being called the slow fuel cut solenoid. It was shot, got one at a junkyard and she runs great now. Good info on this carb here;

Also turns out I may have an 81 CJ with a pacmule trailer available to me in the near future so funny you should mention it. Remember; feedback carburators are fun! Good luck!

GLAD YOU GOT IT!

YOUR CARB IS A BIT MORE COMPLICATED THAN A CJ

MAYBE YOU OUGHTA SWAP THE MAZDA FOR THE CJ?

ANY CJ QUESTIONS, JUST POST 'EM
