Phil...be sure and let us know the results of your work on the motor. Having a motor that refuses to quit is a rather desirable problem to have <G>

Quite often, this little quirk can be caused by a minute air leak in the carburetor area. Not enough to disrupt motor operation at higher speeds, but just enough to keep the little bugger ticking over at low idle when you really wish it wouldn't.

No danger in pulling the fuel line. I've been doing it for 30 years, and still have all my fingers, scar free no less! Keep in mind that the prop is mounted forward of the carb, and just don't stick anything you value in that area. Simple enough.

The .25 DOES vibrate a bit more than other motors, but that's due to the iron piston. The upside is that the lapped iron piston/steel sleeve will, with proper CASTOR lube, outlast other motors by a considerable margin. It's not uncommon for a lapped piston Fox to run 10-15-20 seasons and still be going strong. Good value in the extreme.

Keep us posted...
