Inside the "Triple Nickel"

[Four Paws]

Love my 2260 but be careful with the recoil an decomp. Did this Sat......

broke the post clean off!

What a bummer! Another reason I like magnesium saws. I'd rather pack the extra 1/2 pound than replace a bunch of broken plastic parts. Sorry for your luck on the recoil.

I hear you there but with my hands I can't stand the old sxl vibes!

That's the same exact thing that happened to my 2188!

OK, finally some "inside" pictures.

I've been running Maxima K2 lately and noticing that it seems to smoke more than normal on a cold startup. I think I just found why. The insides of this 555 are majorly coated in oil. That's a good thing!

There is some carbon buildup already, after 1 1/2 tanks. I'm not sure what to thing about that. Probably normal.

There's a puddle of oil on the rod. It doesn't show up well in the picture.

Here's the offending stepped squish band. The very outer band is .008" tall, then the next band is .009" tall.

Here's the squishband post cleanup. It doesn't show well in the pic, but the steps are completely removed. What looks like a small ridge in the middle of the band is actually polished NiSi. I tried to get past that and it was just polishing it.

Sorry about the poor lighting. Not much detail left.

K2 leaves a good film. I think better than belray and about the same as motul.

Here's my timing wheel setup.

I bought a 1/2" bolt, drilled and tapped it to make a bushing. I did the same thing both of my Stihl flywheel removal tools.

Have you noticed more smoke on a cold startup?

 

[blsnelling]

I did not measure port timing before doing the machine work. Here's where it stands before porting.

Exhaust - 105°
Transfers - 117°
Intake - 79°
Squish - .018" (No base gasket. Parts of the base would get too thin.)

That's it for tonight.

Maybe a touch. I don't pay much attention to that though.

Normally I wouldn't either. This was enough difference to get my attention. If it's due to a superior coating of oil, I'm cool with that!

Klotz R50 is the only thing I've seen leave more oil.

It runs just a little on the dirty side as well. Perhaps that's not a bad thing after all.

 

[blsnelling]

Wait a minute! Did I just turn this into an oil thread, lol?

I'm not worried about the dirty running stuff after tearing down. A saw with 5-6 gallons of the klotz. It was a thin coating on the piston.

I'm not liking the carbon after 1 1/2 tanks. Haven't seen anything as clean running as belray. Nice pics keep em coming

I'm still using the Lucas semi-synthetic oil, its cheap and seem to leave a nice film and burns clean.

I have experienced the opposite, less smoke/smell period, when compared to the other oils I've used. Do you think maybe the AT is still adjusting itself, and is running rich at idle and maybe WOT as well?

Glad you finally got your hands on one of those smoking hot little Husky 60cc saw.

 

[KenJax Tree]

You might be right Andy....my AT saws smoke little more when cold than the adjustable carb saws.

I have ran numerous oils from OEM to the high end stuff. The piston crowns all look similar. The ports and combustion chamber is where full synthetics shine. Fuel comes into play as well.

Enough with this oil ****. Is the saw ported yet? I figured you'd be out cutting in the nice warm weather.
