You have to pull some power out to stop the "pop" or four stroke. Mine was less timing or not open exhaust as much.
The mtronic limits rpm with fuel and timing not by cutting spark.
Yes resetting stops the popping some til it relearns.

Mine needs 020 or less advance to stop popping. You have to much advance?
This one was already advanced. After switching from jms to stock to my ported and back and forth 15 times I'm convinced it' the mtronic that won' lean out enough to run that cylinder. It pops progressively less the hotter the saw gets. If I do an mtron reset, it pops twice as bad and gets progressively better as the saw heats up. It's rich and won't lean out more. If i put either of the cylinders I ported on it, there's no popping at all

It's running to close to the programmed rev limit and adding fuel to slow it down. Have you tried putting a heavy load on it with a long bar?

It runs less rpm in the cut than mine and my cylinder doesn't do it. But I agree, the more load, the less it pops

So the "M" in M-tronic doesn't stand for "Maxxed Out"?
Would only be interesting to know, as a what not to do, but then again, there's probably not much one would want to emulate from this mans work.

only if your paying hotsaws101 $400 500 600 or 1000 depending on your level of porting: zipkit-max, insano-max, psycho-max, SS (super sized) psycho maximus!
