Finally got my muffler back from JTECHand they did a great job. It is an excellent fit. I started the engine today and the muffler sounds great. The engine is still new and the rings aren't seated so I'm running it rich to make up for the lack of proper quantity of oil. I'm breaking it in with a 40 to 1 mix rather than 30 to 1. I'm too lazy to rig up another fuel jug for it.
The engine REALLYneeds to be tuned and I'll do that next time Irun it. It's still spitting oil so it has a way to go before the rings are seated and she starts running her best. Ireally like this little 15cc engine. Kinda makes me wish Ihad more 60 sized planes to put them on.
