ArcticCatRider,

I appreciate your advice. I dont have an air-conditioned house, its very well ventilated even by modern standards. I work in the HVAC industry so I know what I am saying. None the less, runs at home ar for less than a minute- usually to finish off any fuel in the carb.

Opjose, relax. The point is I will need to test the engine out myself, just wanted to know whether what I was doing is right. Thats what the forum ios for, isint it. I am not prone to instrumentation for my airplanes. Bax from the OS support forum has also suggested to go for a smaller prop which I was quite surprised with and was unaware of. I will both tach and temp gauge it and report over the weekend
