porting

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...

https://www.youtube.com/edit?o=U&video_id=py1VC11iT8g For sale is an excellent Husqvarna 372 x-torque. This machine is in great shape. The piston and cylinder are OEM. We ported and polished the cylinder so it is a real screamer. It will come with the large felling spikes, 20 bar and 3/8...

Hey all, I've torn down my 026, non pro. My plan is to do the crank seals, new piston, and hopefully clean up the oem cylinder. However, I need your help to know if my jug us redeemable. I'll attach some pictures. If it is redeemable, how do I clean it up? At what point should I replace...

After reading way too many threads on this site about a 50cc/70cc saw combos. I decided that was the way to go for me. Step 1, purchase first brand new saw for me ever 550xp!! Awesome saw, love it, pretty much perfect saw,except for the larger stuff. So now I was looking for the legendary 372xp...

All tags missing on this saw. after some research I believe it is a C-72. It runs well but w best loaded carb tune seems a bit weak. It may have a case seal issue. I figure if I am going to take the time to pull it all down I might as well go stupid on it for the fun. Here we go. What is the...

Hi, this is my first post. I'm from New Zealand and my inlaws bought a Stihl MS261 over for me one thier last visit. It was 60% cheaper to by in Illinois and fly over with it than buying it at the Stihl dealer in town! Its the 4th chainsaw I have owned and is by far the best I have ever used. I...

What you think about my stihl 026?

So, i would like to get some advice for porting my loved ms260. Great saw! Done a muffler mod, but it needs a bit of a waking up. (You know what i mean)

So I know it is a long shot as porters like to hord their numbers! But I was given a 120SI that is in really good shape. I have put new piston in and had to make a velocity stack for it, as finding an air filter was a pain. So anyway just hoping someone will chime in and give me some numbers to...

Started tearing down my open port Husky 55 today. Bought it as a parts saw, because it was bell to be blown up, turns out the spark plug threads were stripped. So I figured I'd pull the jug and fix it and while I'm at it, do some port work and few other misc mods. Has anyone done a timing...

I recently acquired an Echo CS-590 Timberwolf Chainsaw. As promised, I intend to measure the muffler on my flowbench and then measure the incremental improvements as a result of the common "muffler mod" alterations. Here's my saw. I purchased it last week at Home Depot. It was a "return"...

How does M-tronic's affect porting/modding, AND How does porting/modding affect M-tronic's?? #1.) If the muffler is the only thing modded? #2.) If the only thing done was removing catheters? #3.) If the carb is the only thing modded? #4.) If the whole sha-Bang is ported?

Bought a dented up used muffler. I cut it apart with a 4.5 inch wafer wheel. Cut off exhaust exit pipe and opened up hole with die grinder, Opened up two lower small holes in center tube from entrance side tube. Tig welded it back together,painted with rust-o-leum 1200 degree grill paint and...
