After a recently blown head gasket, I replaced the head and cam with uprated parts from Ted @ Engnbldr on my 86 carbed PU.
The engine runs great – mostly – it will cruise at 80 all day long and pull strongly, especially in the right rev band. If I try and accelerate in a gear slightly too high (4th @ 40), it will hesitate and miss.
If I tap the throttle form idle, it hesitates and then picks up.
Before the re-build, everything ran great.
It’s got new plugs, wires, timing chain, filters. Cleaned all EGR parts and checked the routing (repeatedly) of the VAC lines. All ground wires are in good shape.
During the re-build, I did strip the reed valve that sits below the carb. Unfortunately, during re-assembly I got distracted and am not sure if I put the valve plate back in the correct way. It fits facing forward and back. It has an arrow stamped on the plate.
I’m not sure if this would cause my problems – anyone know which way this goes?
Other than this, any ideas on the hesitation????
Thanks
