    Does resetting the saw help?

    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.

    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

    Bullshìt. That's the exact opposite of the truth. The hotter this saw gets, the less it pops and gets stronger

    :cool:

    This one pops like hell after a reset. And pops less as it warms up and learns. It just won't warm up and learn enough

    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

    Ever tried removing the flange? Ain't much room for fuel to move up through the middle of the case. I'm thinking the flange might be helping it
