I thought your post was very interesting. Though I have never been a converter myself, the interest has always been there! I no longer own or have access to the necessary equipment so I probably won't be getting into converting anytime soon. I do maintain a couple of Stihl saws and spent more than a few hours on the back end of one last weekend after a windstorm went through our MN lake property! I've always wondered how they would be as an airplane engine!

I did note you used the original Stihl carb and that the cylinder was of Mahle mfgr. You noted cylinder timing ..... how does the Stihl cylinder compare to a typical model engine's timing? Keep up the good work ..... the posts are interesting for sure.
