I already have 2 & a 357 & a 562, I have to stop!

First I've heard of that.

.008 shoulda worked!

Just a thought, maybe not enough ring end gap, when it warms up the ring binds?

My nieghbor has aquired a 241c and wants me to punch it up a little, (muff mod, base gasket delete, ignition advance) is there anything about this saw I need to watch out for?

Sounds like you have it going, try taking 1 mm off the top edge of the piston, go 10mm in leaving a popup, have it done in a lathe tho. Make sure you shorten those skirts

I did it with a poulan 2900, but as you say it is a lot of work, I did the bearing pockets with sand paper on a piece of pipe, it took me 9 hours. I had good measuring tools left from my machining days, I had to keep everything the same from a starting point. It changed comp from 139 to 164. I...

Starters usually don't live long with that much comp.

I had a like new 281 with no place for decomp, that was too much, it had to go to younger person.

Yeah. I could drill & tap it myself, I have valves. I took this saw on trade, I really don't need it. I am 84 years of ancientness and have plenty of easyer starting saws.

I( have a 55 with no decomp it has a place for it but it is not drilled thru nor threaded. I wish it had the decomp, it's got 180 lbs comp. and it pulls hard.

I have a 55 with 180 comp, I don't remember checking squish but it must be very low, like less than .020.
