The issue I am having is this, this is my friends truck by the way, he thought the truck needed a new carb because the truck was running horribly, stalling not idling properly and such, so we replaced the carb with a newly rebuilt one. After doing so we found the truck would run the same. After checking all vacuum lines and finding no leaks, we finally found a ground wire coming from the ignition coil going to the distributor that had broken free, we re-attached it and the truck fired up! After 10 minutes it was choking down and finally just died. We thought the carb may need adjusting but after adjusting the fast idle and mixture to stock, to no avail, the truck was still acting the same, it just will not idle but will run at higher rpm's. We let it sit for 20 minutes thinking it may be thermal related and sure enough,it fired up and ran for about 10 minutes then started choking down again, then finally died.
My bigger question here is, is this thermal related? I noticed I could manually close the choke butterfly and it would run, but then after several attempts to keep it running, it finally died again with or without the choke closed.
We checked the fuel pump and it is getting plenty of gas to the carb. Fuel filter is new. Any ideas here? Thanks!
