To late..

I milled off .020 off the jug. then I took a die grinder and took .020 of the top of the intake port.
and cut out the in side of the manafold and put on a carb off a us 25cc engine

I took a pice of still that is .117 and brased it to the in side of the side cover.. This cover is made of still not plastic.

I took out the key to the fly well and advanced the timing 6 degres. Wich it about the thiknes of the key way. Put lock tite on it and put on the prop hub.

With a 16x8 prop I am running at 9164 rpms. but it has a bad idel. It will vibrate bad.. I take it up about 1/4 and it will smoth right out.. I do not know why it is doing this yet.. could be the carb or the timing or the .020 I took out of the intake.. I do not know. I will have to play with it more. I did not think about the tork on it.. I will have to see what the trust is going to be.

Thanks for your in put.... but if it is not going to work it was fun to do lol........
