I have a Moki 2.10 that gave me problems on Sunday.
It has 1.5 gallons through it and it is a strong running engine. However I was on my 2nd flight of the day flying the pattern when I thought I would try to perform a blender. After the maneuver I noticed that my Moki was making a sputtering sound. I immediately landed figuring that it needed some needle adjustments as it is still in the break in .

I landed, took a 10 minute break, topped off the tank and tried to start it. It wouldn't start. Finally after about 15 minutes it started. However as soon as I would try to transition from idle to full throttle, it shut off. Each time it shut off it took 15 minutes to start back up.
Any idea what could cause this behavior?
I let it sit for about 1/2 hour figuring that maybe it was overheated. That didn't make a difference. I'm puzzled. I don't think it is the low end as it ran perfectly on the first flight.

Could the blender have caused an overheating problem?
