You can take the screws out and throw them in the lake/river or whatever it's not going to make it backfire. When it backfire it's because you have ignition when an intake(s) valve is open.

a lean condition can cause a backfire.my money is on poor carb adjustment.the engine can also backfire from not enough timing at low rpm.

Some guys skipped the high school automotive class and went straight to the spintron.

A lean condition CAN CAUSE A BACKFIRE thru the carb.

Yea, in NUETRAL I don't know about the engines you build, but I can rev my engines in nuetral, to 2500 RPM with very little throttle blade opening.
