    Dolmar 341 first build

    This is my first proper build, I've done a couple of drill through the muffler type muff mods and a fair bit of saw tuning and repair. Bought this 341 for £20, wouldn't run. Bad fuel line. Snipped the bad bit out and bodged it back together. It ran well then. Next, muff mod. I'll let the pics...

    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

    Was wanting to port my 2011 model 346xp

I was wondering who out of you have handled a ported 346xp, I mean out of the box the engines rpms mac out at 14,500 which is already insane. Curious on your thoughts on the project...

    tl;dr- Which, if any, modifications are worth doing to an out-of-box chainsaw? ~~~~~~~~~~ I'm hoping to understand this a bit more, I learned about two general 'types' of what I can only describe as intentional-weakening of chainsaws (out-of-box) and want to learn more, specifically: #1 - It...

    346xp Frustration

    Hello, I just made an account, but I've lurked for a few years. I recently bought a used 45cc 346 on ebay for probably $100 too much, but definitely too much since it's given me nothing but issues. For the last year or so I've been bucking and felling with a Husqvarna 460, but I got tired of...

    MS461 Damaged Cylinder - Afterlife?

    Just curious ... is this MS461 cylinder toast or is it salvageable? Got this from someone who is tossing it away, figure I could use it to practice grinding. But if it is salvageable, I might as well turn it into a porting project just for kicks. The portion above the exhaust port and...
