I got the little Stihl engine today and it has FS65AV Electronic on the pull start and the magneto is indeed on the case.I noticed it has three magnets on the flywheel.Is this the norm for all Stihl engines ? It also uses a slant sparkplug,which definatly rules it out for watercooling for r/c boat use,although it can be done,but much more work.On the spec sheet it has it is 19.8 cm3 displacement with a bore of 30mm and a stroke of 28mm. What size engine is it in cc's ? The way it sits in the pic without the red cover it weighs 3lb 5 oz.Would it be worth getting it converted to an airplane engine ?
