Carb Heat

PA-12 Super Cruiser

Registered User
I have noticed that the RPM drop when turning my carb heat has reduced to where I barely notice a drop. I checked the carb heat flap on the carb and it works fine. It isn't a tight seal, but I don't think it ever was. Could the air temp affect this or is it a deeper issue.

If you have an O-235 you're not going to see much of a drop. Not like the larger engines.
