On a more serious note I will never buy or accept another mcculloch.

Give it a little more intake duration by cutting the piston skirt and you'll find it's got guts.

It doesn't hurt the balance any? I've never done anything like that or even been that deep..

It was a pretty easy as shown in the thread I linked to earlier. They run quite well stock though. Like I said up thread though, since it does not have A/V I'd probably not put too much effort into it.

Did you open up the exhaust any to cut down on back pressure or am I looking to create more back pressure?

The work doesn't really bother me I mean I'd rather learn on this 15 dollar saw than any of my other saws

I'm just scared I'll take to much off or just **** something up really..

The exhaust port and timing were perfect as-is but I opened up the muffler. This was the thread: http://www.arboristsite.com/community/threads/mcculloch-se2012s-mac3200-a-v-conversion.277788/

I used a degree wheel to determine how much to take off so I don't know exactly how much I trimmed distance wise.

 

[cali6construction9]

I don't have a degree wheel

I'm sure I could come up with something

I made one out of a CD and was going to reference the old thread, but the pictures are gone and I can no longer edit it to fix them.

 

[cali6construction9]

I got plenty of cds lol what degree did you cut out to?

stihl 026 husky 266 xp mac 610 efco 132s craftsman 54cc? mac 1635

 

[Chris-PA]

I opened it up to a duration of 151deg. I did not modify the ports in the cylinder at all, just trimmed a notch in the piston.





Later I changed the printout to one that read to 180deg in both directions rather than to 360.

 

[cali6construction9]

Ooh ok you used a printer? For the measurements
