It might be caused by dirt in one of the screens. What was the power setting? >I had an A&P come out and we started the plane, ran it up, and did a mag >check.

(doubtful) The engine is practically new, and the previous owner I don't think normal plug fouling would cause the engine to quit. If this happened to me, this is what I'd do: 1. Disconnect the fuel line to the carb and look for a good, steady stream of flow. Catch it in something clean so you can see what's in it. 2. Look in the gascolator for water or dirt. 3. If the flow is a good, round stream, remove the carburetor inlet screen and look for crap. Also remove the carburetor and look for dirt or water. It might be too late to find water if he already ran it up, though. It should have been drained first thing. 4. One thing to look for too is the float, and float valve. If the float is able to touch the sides of the bowl, it might have jammed. Also, if the float valve stuck open, the thing would run super-rich, but I'm not sure what that would do on a full-power takeoff. Does anyone here know? Sticking closed would be a bad deal, too, but I've never heard of that happening. BTW I'm not an A&P, these are not professional opinions! Just the things I'd try, based on experience with a lot of lawn mowers. heh heh ---------------------------------------------------------------- Steve Dold ([EMAIL PROTECTED]) http://home.pacbell.net Say NO to useless over-quoting ----------------------------------------------------------------
