Hey all. I'm having some problems with the choke (I think) and a stumbling that almost feels like a miss at middle RPMS while cruising or throtle is held steady.
When starting cold, it takes about 30 seconds of cranking to get it started. It does "high idle" once it does start. The truck idles and runs fine other than this. I rebuilt the carb 3 years and 70k ago with a NAPA rebuild kit and have had no problems at all since. New plugs, cap, rotor, wires, fuel and air filter all within the last year. All the vacume lines and electrical wires and plugs look fine. This all came about when I let it sit for about 3 weeks.

Any ideas?

Thanks, Dan

 

UPDATE.
The "miss" at steady RPMs is gone. This makes me think it's electrical. Right?
Just a little more info on the starting issue; Back when it started right up, I used to pump the gas pedal 2 or 3 times and it would start right up. This seems to do nothing now.

Any thoughts?
