It's not rocket science. Check the needles... Gassers DON'T smoke or shouldn't smoke... It's bad for their health, go figure!

Check your manual for the correct settings initial or give the guys at Desert Aircarft a call for the skinny.

The needles are identified on the carb body adjacent to the needles. BUT the LOW needle is closet to the engine center line.

Just to know where your at run them down (CW) to a light stop recording where you started at
by noting the revolutions or fraction thereof. This will give you a baseline.

It does sound like it maybe a little rich. Any hesitation or lazy transition? Will it idle forever?
