Well I did something I have never done with the KT powered 417 this year. I always buy 100 octane aviation fuel to put in my seldom used small engines. Things like my generators, chainsaw mixes, snowblower, etc. I dumped 2+ gallons of the expensive stuff in the 417 and mowed yesterday with it. What an incredible difference. It was like it had new points, plugs and a perfect timing adjustment done to it. No hiccups, steady power in high grass and no excessive heat. Oh and it has a racing fuel smell to it that I always loved! I actually had a smile on my face while mowing. Just had to share it!

The governor settings on my refinished Series II 417-8 just cannot be fined tuned. (It had the same issues when I got it so it isn't new from the refresh). I think the PM may have bent, (in or out), the governor rod at one time. The spring looks good and there is no play on the Governor shaft and it moves the same with the same pressure against it as my series I KT17. I have adjusted the throttle cable location, moved the spring and rod to different holes. What I have is an over-rev at wide-open but when I find the RPM I need at full throttle by adjusting the throttle cable, when I shut down and come back to it, even right away, I have a idle all the way to full throttle. Right now, I have it workable but only at three-quarter throttle. If I go past three-quarter open, it goes over 3600 RPM. Motor has about 1280 hours on a working hour gauge. Greater than 100 PSI in each cyl now that I have run it some. It was about 90 and 95 when I first checked it. I noticed that it does hesitate to come down from a higher RPM. Not instant like it should be. A trick? Something I overlooked? It runs great! Thanks in Advance!
