Ok the truck is super clean, runs great, but when I give it more than half throttle it hesitates and bucks and goes but is weak.
I think it may be something with the big jet cause I watched the idle jet just drip like it's supposed to and the mid spray really well and the big one kind of trickle?
But has new cap, rotor, plugs, wires, timing set to stock, air filter and fuel filter.
And I ran two tanks treated with Lucas fuel treatment. The truck runs perfect!
Besides at more that half throttle, and only twice it ran great for a min.
Is there valve that could stick inside the carb? Or scrub the jet?
