port

Couldn't find a 620 (heck my 590 was a floor model) so am very aware that upgrading to its carb and/or coil may be worthwhile here, I'm going to do a "tinman style" porting job (if anyone's familiar w/ his recent 590 project) but have also read most of the old threads here and on OPE and feel...

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...

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.

Looking for what you would do you your 372 x torq. I'm going to throw a new jug and piston in mine and rebuild carb along with a muffler mod. Is their anything else I should do while she is apart that doesn't take anything too fancy or complicated to do?

Hello all, Long story short, I bought an Echo 450p and am using it to try my hand at modding a saw. This may be a little drawn out as I'm going to work on it as time allows. Initial plans are to record a baseline, muffler mod, base gasket delete, possibly cutting cylinder down, port and...

Hey all, on the verge of buying a 372xp xtorq, not sure if you can buy the non XT anymore or which is better, but I was thinking to put a big bore kit in it, and lightly porting it also. and I imagine the ignition would need to be adjusted with these mods also. Living in B.C. Canada we have...

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?
