not so easy. his has a 10mm hole & mine has 8mm hole. enines are same but prop adapters are differrent. I could bush his down I suppose.
I plan on working on it tonite but won't be able to get in the air till Thurs eve. Think I'll do one thing at a time so I know what fixes it, although that will drag it out a bit.

I am also thinking of switching to his carb to see.
