My RV12 with the 912ULS will not run smooth at WOT or get T/O power after it's HOT. Last flight everything was fine until I left the power up at altitude to see what I could get for RPM in level flight. It stated to run rough at 5400 RPM. After returning to the field I as unable to get more than 4400 RPM. The problem is always after the engine is hot. Don't waste your time with suggestions to trouble shoot only because we've been through everything at least twice. But please, if you have had or know someone who has had the problem of not running at full power after the engine gets HOT, I'd love to hear what fixed it. Ron PS; I realize I'm just a lurker on your forum but I'm about to make Coors cans out of this airplane and could us someone's help to prevent that.
