    Hello, I was wondering which engine to get for a replacement. I am considering an O.S. 18 CV-R ABC. I know it's a good, reliable motor. I have the stock .15FE motor which puts out 0.56 HP @ 29,000 Revs. The O.S. puts out 1.35 BHP @ 28,000 revs. I know the biggger one is better, BUT, my question is will I see the difference in the performance. I hate to waste money on stupid things and I am counting on some opinions to use as a guide. Thanks!!!

    I sent my 15fe to this guy and he resized the sleeve/pistion and modded them for more rpms. Also bored out the carb for me. I will be getting it back today. Its suposed to be much faster now. Total cost $45 with return shipping. If its as good as he said its a great deal. I will let you know after I run it!
