    27HP kohler loses spark and then comes back for no reason

    kinda tough to say without seeing it. im no real mechanic just can dabble in most stuff. possibly check all wires and connections also. maybe get ahold of the guy you sold it to and see if you can borrow one to test off the old or new motor?

    Anybody know anything about the guy who ported this 550XP?

    apparently this guy just has loads of horsepower sitting in his pocket and he chooses which saws are worthy of it. who knows since he was in r and d maybe he build himself a dyno/autoloader to put load on saw while doing the perfect breaking techniques. two gallons of idling fuel thru a saw is...

    27HP kohler loses spark and then comes back for no reason

    could be an issue. but if its not dieing while its running that would assume it cools the coil well enough. its the after shutdown heat increase that might be just putting it over the edge. the constant cranking afterword could be enough to cool it down. try maybe just cooling off the coil or...

    Mastermind Meets The Stihl MS440/460 Hybrid

    Ill worded on my part. Was talking about the transfers entering the cylinder top side of the piston. I really appreciate you two (randy and brad) sharing your knowledge

    Mastermind Meets The Stihl MS440/460 Hybrid

    So after our 660 talk today I started into this 44 with 460 top I got. How did you determine how far to push the transfers without sacraficing velocity? And do you do anything with the piston windows?
