Well I certainly don't agree with that conclusion. (What you were told about having to run a flywheel...) I have a Homelite 30cc with a lot of flying time on it. It DOES NOT have a magneto, and it is all hopped up and turns an APC 16 x 8 prop at 9400 rpms!! No problems with the crank nor the bearings. A lot of the boat guys run these things in the 10,000 rpm range, again without a magneto. I have also turned a lot of 25cc Homelites some very high rpms, and I don't ever use magnetos!!
