Cool now that thing will really come to life.

It ran really darn well with M Tronic!

It ran really darn well with M Tronic!

It had lots of torque, but man it needed a helleva load to come to life. Now with a proper tune, you’ll see what it can really do.

Uncle Heath, My point is, this is a STROKED 661 build!!! An old school build ought to have an old school carb IMO, especially one built by Nephew Johnny. None the less, an amazing build by quality people who do top shelf work. I'd take this saw no matter how the fuel gets delivered.

Couldnt hold light, phone and rev at same time. Its idling at just under 25* btdc. When light kicks revving it is about 20*.

Uncle Heath, that picture means nothing to me, I'm not that smart. If the "piston wash/carbon build up" is a good example, I will take your word for it. But, is it due to the oil, the port work, or the MT?

Although I don't own one, I have nothing against MT. I just don't have the cash or the desire to replace all my carbed saws with MT.

I would guess piston wash has more to do with the porting than the carb being mtronic no? Just curious.

That saw ran great with M Tronic!

Shouldn't the timing advance more with RPMs than at idle???

25* btdc at idle
