Our 0-200 runs on the UL91 from the same pump with no problem, we have our own problem of high oil temperature. Originally he used 100LL but UL91 became available in the winter and he has used it until now but the weather has become hot. Hopefully Roger will know if it is the carb needle that requires adjustment. Clive G CBDG 601HD 0 200 590 Hrs.

Something else is going on. I would pull the carb tops off and check the needle positions. The clips should be in the #3 slot. Third slot down from the top. If it is in the #2 position it could cause rough running depending on elevation or altitude. It would be a little lean. Those OAT's aren't an issue. That's 70F to 84F. While your checking the carbs double check the bowls and make sure it has had a carb sync. Make sure the plug gaps are at .023 - .027. -------- Roger Lee Tucson, Az.
