262 rebuild

[Johnmn]

Rebuilding a kS 87 262 and have a few questions. I was gonna just use a meteor piston but got reading and saw they are shorter than an oem. Should I still use the meteor or is the oem worth the extra funds? Also I want to give her a mild port job should I just widen the exhaust to 65 percent and leave the rest or does this saw like more intake as well? I see most guys are doing bridge ports but don't think I'm there is there lots to be gained in the transfers?

I saw no difference in the piston height when I used a Meteor in a KS cylinder. That being said, it was a bit snug with the base gasket delete, so I'd recommend .023 for squish.

There are also those out there who would be reluctant to port a (uncommon) KS cylinder, as they don't feel there is that much to be gained .... myself included after running both.

Just my $.02.

New oem Husky isn't that bad on price now.

yeah, I personally wouldn't use the rare cylinder head to port. but thats just me

The 262 i rebuilt and was too tight to delete the base gasket the 257 actually hit without the base gasket i did port my 257 but didn't the 262 it was a strong runner anyway.

Degree your cylinder.

A good 262 cylinder is one that cries for a popup piston.

You'll gain compression and intake. The only two things you need to turn a great saw into a greater saw.

You can adjust your no gasket squish easily that way as well.

Like Al said their are more their just unleash the beast lol.

I wouldnt fool with a 262. I will buy it from you and you can put the funds towards a 562.......

I fooled with my Mahle 262. It's happy now.

... as was my ported one. VERY strong saw ... very happy me.

Nothing wrong with meteors btw. The crown height/comp height can be a bit different than oem, I've seen as much as .004.

What size bar can't decide between 18 and 20? Working on my 40,60,80cc plan with multiples of each was thinking either 16,18,20 or 16,20,24 lots of hardwood here

I somehow end up running a 20 on my 372, 357, and my 346. I still have a 16, 18,24,28, and 32 on hand, but I don't like to bend over for ground work with a 16 and I don't like sharpening so the 20 ended up on the 372. It makes chain swaps easy too.

It's all about what you're cutting. I cut logged out hardwood tops the most. I just pick the saw for the speed I feel like cutting.

I'm going to have to degree it, I have read about guys sanding the squish with sand paper attached to old piston is that hard to do? Or should I just be happy with whatever the squish ends up at with gasket. Also I realize that this is a rare cylinder but I am not building this saw to self it I plan on using it and a lot! So grinding on the cylinder doesn't bother me one bit I was thinking about smoothing out the lower transfer casting and widening the exhaust and that's it, maybe the intake seems fairly good size?

Instead of using a piston with the sandpaper, I prefer a small sheet of glass.

Just my $.02 ..

If you sell it I might know a guy

To sand the squish band? Do you cut the glass the size of the piston and glue it to something?

.... for sanding the BASE .... the BASE ....

[emoji106] lol. I agree.

But I DO remember a builder video (Tree Monkey) where they used a mandrel the size of the cylinder with self-stick sandpaper to cut the squish band ...
