what kind of pop like fuel backfire ? or mechanical?
seems like a fuel backfire I changed it back to everything stock besides the base Idle I added 225 to the whole table and it didn't do it
when you put in the cam where you tod? top dead center on number 1 piston?
base running air flow did you do that as well and you going to have to make sure you you high octane and low octane tabels are the same.. and you spark idle ya need to bump you you spark at you idle spark advance in you park and dive as well..
Yes! Base idle is the only change in it now bit I tried it a minute ago and it did it ok thanks I'll check it out
the throttle cracker as well if your idle hangs after you let off
