Nothing could be easier than setting up a gasser...
ONE line from the clunk in the tank to the fitting in the body of the carb...
ONE line from the tank vent to atmosphere...
NO line to the fitting on the steel cover on the carb...
Open both carb needles 2 turns...
Start engine..
Set high needle for max rpm, open about 1/4 turn..
Set idle speed to about 1800, slowly close low speed needle..the rpm wil increase...
Reset to 1800, lean some more, try transition...
Repeat until the transition doesn't work...
Open the low needle until the transition comes back...
Re check the high needle...
Go fly.....
These engines are not plug and play, it takes a little fiddling around to get the correct settings...
