Hi all
A fellow pilot has found his 912UL will not start on UL91
avgas now the temperature is high 21 to 29 C.
after checking every thing he eventually changed one
tank to 100LL and it starts ok, changing to the tank with UL91 it runs
very rough.
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.

Hi Clive,
The temps should have not made any difference between the two fuels. 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.
