porting

Ported only 3 or 4 cylinders with it $350 shipped

Husqvarna 41 a toy with serious fun!

Been a while since I’ve posted on here, I’ve been getting into porting saws lately and just finished a silver tag open port 50 Rancher Does anyone have some advice on changes I could make to have it run faster if I did another one? I know it could use a bigger carb and a little transfer work...

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...

after 1 year in use

Hi everyone, I’ve been sorting through searched threads on here but couldn’t come up with a general consensus on which maybe the best direction to go in for my situation. I’m a full time,production arborist who recently got into porting my own saws. I’d like to pickup a lathe to advance my...

Hello all! A pleasure to finally get an account here. I tell you, this lovely site and acresinternet have been saving my dad and I saw mechanical woes since the 2000s. Lately, a massive thanks to pioneerguy600 and droppedp51 in particular as I have gone down the pioneer rabbithole and have...

After rebuilding this turd saw from 2 different saws a ms260 and 026 i kept it mostly with 026 parts except 1 case half, so after bunch of testing and working up in steps to porting this 026 (48.7cc model) After not satisfied turning a 16 inch with 325 i start to port this saw I was on...

Hello am selling a very nice Husqvarna 262xp saw. I got this saw in a trade. So, the story was it was the grand dad's saw and sat on self... blah... blah...blah... yadda yadda yadda . Needless to say the saw needed a piston :dumb2:. So this saw was completely taken down scrubbed doctor clean...

Anybody have and good numbers that will work on a 142? Should I leave the intake alone and do exhaust and transfers only?

Hey everyone! First time chiming in here. I love the forums by the way! So I’m planning on doing a port job on my ms361. Just wondering if anyone has some good numbers to start with or any ideas to go off? Not planning on anything super crazy. Maybe just a good woods port or just a tad more than...

Hello to all, so I acquired a Jonsered 630 that came with a 670 top end. someone had started the work and give up, quit or was just a little in over their head. This is what I have so far; Squish is .024"/.025" Ex 102 Trans 123 In 74 The exhaust and transfer numbers were...

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

Title pretty much sums it up and I've done the research on HOW to do it. Still probably going to get stuck lol. 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...

Hey all, I am a newb on here, but wait before you slam me with the filter and muff mod stuff. I bought a early 10mm stihl 044, its a 120's serial number. Compression is 125psi so I pulled it apart to have a look. Lots of nasty piston skirt scoring and scratches. Base gasket measures 0.040" which...

HI all, first post for me here although been lurking for some time. I have a very low hours 480CD that I use for occasional milling- mostly canting larger trees in the woods that i cant get my bandsaw too. I have basic knowledge of porting 2 stroke engines- mostly high performance...

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...

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...

I have a 372xt that I would like to get ported. Who will work on used saws? I'm looking for porting that will leave the strato ports moving air. Thanks
