I recently posted that my 149 was running beautifully and then it shot flames and died with no compression. I left if in the back lawn for the night and came back to it the next day. Wouldn't you know that it started right up and ran fine again. It runs fine for about a half hour or so then shoots flames out the exhaust and dies. Same result, No compression. The funny part about it is that i run Marvel Mystery Oil in my Kohlers and i usually dont have valve sticking issues. I have to admit, i have not done the De-carbon on this engine yet so that will be my next step. My wife is scared of this tractor now and wants me to go buy a box store tractor.....We all know that is not a option. What do you think?
