poppin thru carb ??
Dont forget it could be a wipped out cam lobe its what I discovered with my 886 Powerwagon !!!

He said it is popping in the exh, left side only, not out of the carb.
I mentioned wiped lobe in post #12.

I doubt it is carb/fuel related if it is only popping one one side of the exh.

Do yourself a favor pull valve covers off one @ time and make sure ALL ROCKERS are COMPLETELY functioning as they should
Its takes little time and then move forward if this reveals nothing .

Check the distributor cap for cracks and burnt contacts. Couldn't hurt.

rule of thumb,..poping out the carb is a ignition issue,..poping out the pipes is a carburation issue! but id pull valve covers and check for a whipped lobe or a bent push rod,...rocker arm issue!

I dunno man...I saw a 383 in a B body popping out of carb,and it turned out to be a valvetrain issue...rocker arm fell off pushrod...not shaft mounted. Ill never know what folks problem is with the shaft mount rocker arm system...

re read my last line.... gotta get fuel in before it can be burnt (air-fuel-spark)

The 383 I mentioned had a rocker off an exhaust valve. The fuel was getting in

and combustion was happening... exhaust was coming out the intake valve the

next time it opened and popping through the carb. Purely a mechanical issue. If

I recall correctly you posted that carb popping was "ignition" which would imply

electrical. Which isn't always the case. that is what I was pointing out. Things

aren't always plugs and wires, you have to pull a valve cover and check and see if

a cam lobe is wiped out sometimes. I say this because I listened to the guys

engine saw how much pressure was coming out of the carb when it backfired and

said "that's valvetrain, pop a valve cover off..."
