I have replaced the spark plugs and wires and the cap and rotor I have also replaced the larger fuel filter under the cab of the truck. My Question is when I start out from a stop there is some hesitation, also it seem to run better when cooler than hot after have been running for an hour or two. Some one told me about some pins in the carb and blowing them off and putting them back. I know my way around an engine, but not that good. Can you help me or talk me threw it. Also a drawing of what I'm looking for might help?

Hesitation as rough running, ie the rpms bogg down, engine bogs down, or just when the pedal is pushed theres no response for a few thousandths of a second.

Need soem details first of all. When it happened, temperature? Uphill downhill flat
