Hi, I recently had my boat out and have a 3 hp evinrude as a back up for emergencies in case my 120 chryler breaks down. Anyway I started this little motor to test it out and it ran for about 3 minutes and I beleave it siezed up it will not pull start or budge. I probly had the wrong oil mixture...is it hard to rebuild? I was a auto mechanic for years but never worked on 2-strokes...will the parts cost me much? I bought this motor for 125.00 I really want to rebuild it....it appeared to be one hell of a engine!!!!!!!!! Thanks for any help!!!!!!!!!
