Ok, carbking, I did a lot of tooling around today with the truck. Fuel lines are clear, nice strong stream running out of the fuel tank. I blew the line out with air(just to ensure there were no obstructions) between the fuel pump and fuel tank( i disconnected both ends and let it blow free)
I bypassed the new fuel filter and ran a straight fuel line to ensure there is no restrictions of flow
and lastly, i removed air cleaner to verify the accelerator pump shoots fuel into the carb when i look straight down. its a nice powerful stream kinda goes away as the engine reaches a level rpm.
There have been zero changes. In neutral, i can rev the engine up nicely with it not bucking a bit. but as i get towards the end of third gear, if i dont let off the pedal, it will start to lurch back and forth in the seat.
I will do a fuel pump check soon when i get a 2nd hand, but i cant do both at once right now without my rig catching fire.
Does anyone think this is a timing issue or anything?
Any other suggestions? I did not personally rebuild the carb, but a very good mechanic friend of mine has, i havent talked to him recently but i doubt with his experience that he did anything wrong. Anything however is possible.
