    Can this program be used to calculate timing duration for chainsaw engine?

    Does anyone use computer program for calculate port timing durations for chainsaw engines? "Rexxys mopedprogram" works great for 2-stroke engines with expansion chamber exhaust. Can it also be used for engines with "back pressure exhaust" ? Here i inserted numbers for Husqvarna 254, year: 87

    Sold 254xp parts

    Might be a long shot but recently got a 254xp with good compression but needs some extra stuff. I’m looking for a good coil, switch, muffler, and starter recoil. Interested in parts saws as well. Thank you
