Well, Vern....I've been readin along and I might have missed something, but I might be able to help you out..
First of all....rule of thumb is....If you need to choke your engine to get it to straighten out...then you're probably fuel starved. When you pull the choke, you reduce the airflow in, which makes it run better because you improved your air to fuel ratio.
It can be anything from a fuel filter to a poor fuel pump to a blocked port inside of your carb.
So think along those lines....maybe you can figure it out.
Of course, I might be wrong.
The truck is rough, but hopefully a good one some day! I've replaced everything from the gas tank down to the carb, which I rebuilt (perhaps badly). So, there's no clogged filters and the pump is new. I've only run ethanol-free gas through it so far. Based in the condition of the carb (was really crusty and pitted on the inside), I'm hoping Santa Claus (or a thanksgiving turkey) will get me a rebuilt one. Just trying to eliminate other problems, such as something with the distributor.
