Oh yeah...worked on it for about an hour today and it just would not run right at all. NEW glow plug (OS #8) and tried 15% fuel. There was literally no change. The top end is great but the transition sucks - the fuel just spits out the carb and the thing dies unless you really transition slowly. If it's been idling for more than 20 seconds or so - forget it.

I'll take it apart maybe to see if there is anything really wrong with it on the inside. It had been running acceptable a few weeks ago and nothing really has changed that I know of except how it runs. We'll see - I don't feel much like pursuing this to death - it's a club engine and not mine. I'll give it back to the fellas at the club and let them figure it out.
It is very frustrating...I even changed the tank at the field...
