Hello Everyone,
I have my first 4 cyl engine, a Saito .72 brand new in the box that I am breaking in per the manufactures specs. So far I have run it at 4000 RPM for 10-15 minutes and closed the high speed throttle from the 2 1/2 turns to 1 and 1/2 and started running it up never more than 9000 RPM. I have ran 1 tank through it and started on the second. About half way though it seized up and stopped at about 6000 RPM. I had it running for about 15 minutes at idle before that. I was sure it was frozen. I worked some after lub oil into it and everything loosened up fine. I tried again and the thing is smoking hot after about 2 minutes and the spit test flash boiled. I have a 12X6 prop and am using Cool Power "Green" fuel at 15% nitro and the correct factor installed glow plug.
The last thing I want is a dead engine, can anyone please provide some guidance?

Thanks
Lefty
