I am out of ideas on why my 77 Bronco will not start when hot. Below is the story.
Before I rebuilt the engine completely, it was doing this. It has new pistons, heads, cam, crank, gaskets, intake, carb (rebuilt edlebrock 1406) etc... It will start up set at about 10-13 BTDC an run great. After it warms though it will start rough idle and won't restart if shut off. If you retard the timing to about 30 BTDC if will start when warm but not run well.
Replaced Parts:
Complete Distributor,cap,rotor,plugs,wires (all new).
Ignition Module (3 times)
Coil
Solenoid (2 times)
It will smoke a little out of one pipe after it warms. Not sure if the smoke is from prior build up in the pipes from old engine burning off. Also valves will chatter at high rpm's when hot. Could this be a problem with low compression in one of the cylinders? This is the original motor, not roller engine.
I feel I am missing something I am unaware of.
Any ideas are helpful.
Thanks,
