Dear Sirs:

Last problems related to carburation were solved changing the carburator for a new one. Now I can set it correctly, but one of the problems is still there.

"Two post" ago I talked about a small hesitation just leaving the idle condition. This hesitation is still there. Considering that the carburator is new, I'm starting to think something about the ignition. What do you think? Once, this hesitation changed the direction of the propeller. Fortunatly, she was on the ground, not flying. My idea is that the ignition may be a bit advanced, but there is no way of adjusting it ...

Any suggestion? What can cause the reverse of the propeller? A lean mixture? A wrong ignition advance setting? Propeller is Mezjik 23x10, not too light ...

Thank you in advance.
Regards,
Javier
