Chainsaw Repair

I just picked up a used but good condition 350 on the cheap and am looking to do some mods for more power out of it. I tore it down yesterday without trying it in any wood, but it seems to run well, 2nd pull starter every time. Looking closer the piston is the dished type and I plan to order and replace with a Meteor 353 piston. The engine has a good bit of carbon inside on piston and on the plug, so it doesn't look like it was run lean. Got the carb off (pita, btw) and see there is still the plastic intake clamp so I will have to replace it with a 372 metal clamp. What have other done to theirs for more out of it? Maybe try my hand at a little porting, but would be my first go at it so any info is appreciated! Thanks.

Check squish before you take it apart, check squish with new piston with out base gasket, I opened the exhaust port up a bit side to side, not on the height.

+1 +1 on what 660 and alsled said.

Thanks guys. Before I pull the p/c I'll try to get the squish with a piece of solder. When I get the new piston would it be ok to use the clips that come with the kit or the factory circlips on the current piston? I have heard some aren't as good.

IMO if you happen to get the meteor c-clips that are double tailed (pass on the meteor 2 tail ones) use the oem if they fit the groove.

I have had no problems from the single 1 tailed meteor clips, if that is what comes in your kit use them.
