Is the choke/fuel enrichment system working? The lever for fuel enrichment can come loose. Motors run ok on the lean side, when they are warmed up.

If its very intermittent and goes away when warm, I would say all is normal.

You could open your a/f mixture screws around 1/4-1/2 turn each and richen it up-should go away.

Mine will queef a little bit when stone cold if I open the choke fully to soon, I would agree that it's probably not a big problem as long as the choke works on all carbs. I can see where the fingers that pull each individual choke could come apart and I'll bet that would cause excessive cold popping.

Mine does it also when cold. Once warmer up no issues at all.

Mine have both done this for many years. I set the carbs up this way cause it doesn't foul plugs if left idling.

Yep.....when CV carbs get warmer...they get richer. When they are cold they will be on the leaner.

If you want to do something.....try the shotgun. With the peashooter you are just dribbling in cleaner and hope that it removes any clog. The shotgun will blast away obstructions with compressed air.
