262XP Day

[M&Rtree]

I have a 357 that's around 10 years old and never had that problem. I like it better than a 262...

357 is a dang good saw.

357 is a dang good saw.

It's JUST a Husky critter

It's JUST a Husky critter

You mean there's other kinds?

If the 562 would have had this crappy chain......it would have lost.

Jon messed this one up........that's my story......and I'm sticking to it.

Is that my 262 in the video? Just asking buddy

Looks like a 268

 

[cali6construction9]

Thanks I cross threaded believe it's a 266. Third pic down see how the air cover flows into the handle the 268 it's squared up and the 268 they started using paper filters

Here's 262xp cylinder that I've worked over a bit...103 118 72 timing...cut chassis to get appropriate squish with a gasket. thank you mm for timing recommendation....

Nice!
When you say cut chassis, do you mean the case, or the base of the cylinder?

 

[Mattyo]

I cut the case on the Bridgeport mill...



Go to the 11 min mark...this is a 385xp ...but soon I'll have a vid of the 262xp

This way I'm not machining the cylinder head except for adjusting timing

 

[Paragon Builder]

Why do you prefer this way? Pros/cons?

 

[Mattyo]

Lazyness.... I don't really feel like diggin through bits and doggin up a head on the lathe.... If I had my own shop i might set it up so its easier to do the lathe work, and cut the base of the cylinder and the squish band as well...but I'm working at my father's shop, so I do the best I can. Plus, I prefer to retain a gasket... so what I do is check squish with a gasket, then cut the appropriate amount off the chassis, and recheck squish. Usually I come pretty close to .020"

 

[Mattyo]

One downside is that I don't get the uptick in compression that MM gets by cutting squishband ....so it would make sense for me make a popup, but I haven't done that yet. I would also need to to take an additional .030 off the case to account for the popup. They way I do it as is, its still possible to go back to a stock jug at any time

Why would you need an additional .030 for the popup? Isn't the idea to keep the squish tight and the popup is just in the combustion chamber?
I've got a 181 that someone milled the case on and wondered why? Achieves the same goal I guess so that's great! Different methods, options!![emoji106]

 

[Mattyo]

Because I'd need to machine off .030 of the piston to attain the popup, which then messes up the timings of everything unless I lower the cylinder head further...yes...options

Oh ok. I was thinking you would weld on a popup.
Got it.

Yeaa speaking of welding I just got a miller deltaweld 300

[Mattyo]

There was a guy on this site welding a popup ....was over 230 psi compression!!!

I'm good anywhere between 150 and 200 myself...

Yeah you are probably there already just cutting the case down for squish.
