Excuse the excitement but I now have bragging rights.
Here it is.

Moki Ultra 20/10 prop 7660 rpm on no nitro fuel.

Saturday after I flew the Hots with an 18/8 Bambula prop and having weak performance, I decided to call Jim Gerard. Let me tell you he is a great guy to deal with. The short story is that I was doing every thing right, I just had a sick Moki. I told Jim I had a Moki Ultra on its way to me and I would run one more test. The Moki Ultra 20/10 is the gold standard and should hit 7600 rpm.

I was so positive that my 2.10 didn't have a chance to do this that I took the motor out of the Hots. I even took out the tank. Put the motor on a test stand and waited for the prop to come in.
Tuesday after work, the prop was in my mail box. I drilled it out, put it on the Moki and hurried to start it before the rain came.

I flipped, I flipped, I flipped, did I mention that I flipped that stupit prop for about 15 minutes without so much as a cough from the motor. I mean I was mad, I flew this motor at least 40 times and its a "starts on the first flip Moki" you know! its just not a problem to start. Well the rain came and I had to stop. Later that night it came on me. The Moki was taped for a Cline regulator and the vent was open. DUH!

Yesterday, I hooked the Cline regulator back up, flipped the prop and the motor was running. Full open on the carb, grab the tach and saw 7660. Thats the magic number that Dave Gierke talked about when he tested the Moki 2.10 for MAN. That motor was humming.

Oh by the way the Moki Ultra prop is beautiful, best looking prop I have ever seen.

So what was wrong before? Well, I don't know. My best guess is that some where I had a fuel restriction, perhaps a partial kink in the line. All I know is on the bench it did what it was suppose to do.

Love that Moki, and the Ultra prop.
