Thanks av8tor1977,

The problem with the idle is that the engine dies when I try to idle it down. As a matter of fact, right now, I use the throttle to kill the engine. By closing the throttle all the way I can kill the engine after a flight.

This engine has a Borg Warner carb on it. Not too familiar with the regulator hole on it but will take a look at it when I get home.
