The hurricane weather has not allowed me to go out to the field. When it is good enough to fly, I happen to be at work. Rats! Today, the sky looked beautiful but the tree limbs were bending to the point that I felt flying was not a good idea.

Yes, mine does start backwards at least once an outing to the flying field. It doesn't correct itself though, and therefore has to be shut down to restart. I cannot clearly remember the circumstances, but I think it had to do with over-priming and not doing the backward flip of the prop. Sometimes, moving the throttle back and forth works.

I don't recall for sure, but I think that I did read that the engine is available as a pusher version.

My initial problem with the Moki was that it would stop running minutes after becoming airborne. Oh it transitioned impressively on the ground, but not in the air. It was more prevalent when starting a vertical climb. Such as a loop or stall turn. A fellow Moki owner in Wisconsin was experiencing the same issue. He tried lots of different ideas and suggestions on his Edge 540.

Mr. Gerard had suggested that I try my initial tuning with about 4 ounces of fuel in the tank so as to simulate the last few minutes of a flight which was related to something he referred to as fuel weight. That is, fuel pushing down and out of the tank, (not his exact words but my own). The HS needle valve was to be leaned until 9,000 rpm was reached, and then, it was to be backed off about 300 rpm to compensate for the beginning part of the fuel capacity. I am not an engineer or scientist and therefore cannot explain his entire script of instructions. On a different and larger engine that I have, our engine guru set the needle valve utilizing the same procedure which gave me one sweet running engine.


I would hope that Mr. Jim Gerard would read this post and put his instructions in for me and others to copy/paste.
