85 22R not running right...
Been working on a friends 85 22r equiped pickup. It ran like crap, he ended up replacing the magnetic pickup in the distributor and it was running great. Drove it all over town the other day with no problem. He got home, it sat for about 40 minutes, now it suddenly runs like crap again. Just like before the magnetic pickup.
Replaced the fuel filter, plugs, wires cap, rotor, checked the timing. It idles rough and wants to bog down down as you give it gas. It appears to be getting fuel just fine.
It looks like it's blowing fuel up out of the carb as it revs. Like maybe a stuck valve?
I haven't dealt with these particular motors much, anything I should check before tearing into it?
