Solving a Misfire

Good work on the tune up and lifter adjustment, but what else can you tell us about the mis fire?
Is it at idle only? Does it change as the motor warms up, is the mis fire out the exhaust or back through the carb?
Also, can you do a compression test. Many auto part stores have loner test gauges.

It starts immediately when engine is running. It seems to be less noticeable on fast idle, but on curb idle it is obvious. Once it’s warm it has “puff-puff” out of the tailpipe.

It does not seem to be an issue while cruising. I do not hear of feel a miss if the car is moving.

I was going to do a compression test but I was too late to the parts store and they closed on me. I will get a compression test done over the weekend.
