Hey Randy, would you mind modding just the muffler and sticking it back in that log? With what porting didn't do for mine, I really want to know how much the MM did. BTW, I've been in the garage the last couple of hours working on the carb on mine. It's back up and running with quite a bit larger venturi
It's much too late to make any cuts with it though. It does at least run though.
I found something of interest while I had my carb apart. There's a needle in the face of the carb. Once you remove the filter adapter, it's right there on the left. It's sealed with a small o-ring and is about 1 turn out. I'd sure love to know what it does!
BTW, the exhaust on mine is still at 106°. As low as compression is on these, I'm thinking a squish band mod is in order.
