I inherited my dads 1967 ford f250 2wd with a transplanted 390 cid and a C6 automatic I have been fighting the timing in it has kept burning the point and that is fixed now then the carb started loading up and I rebuilt that and it was running
Now it will idle and then slowly load up after 10 mins but it will clear out if I raise the engine speed
once it clears out it will load up again and I can clear it out again
not when it is running at a higher RPM than idle if I put it in gear it will load up and back fire and cough and die
do I have a modulator issue?
is it something when the trans is engaged that it will leak air?
but why does it load up and back fire?
Thank you so much for your time
have the same problem?
