6-cube deluxe

[cus_deluxe]

So theres lots of stuff thats been covered that i can skip. Overall impressions are that all the parts in this kit fit together better than any other aftermarket stuff ive had (plastic is good, holes basically line up etc...).
We'll start with the bottom end assembled, went together nicely other than a little operator error on the pto side seal haha.

Cylinder looks pretty good overall. Cleaned some boogers up and made sure everything was beveled well enough to run and thats it.

Ring end gap seems good, bore was within a few thousandths in diameter.


Piston looks nice, no voids or obvious casting flaws, pretty close to round too.

Assembled with stihl oem wrist pin bearing and clips from @Definitive Dave , no base gasket, squish is maybe a little tight but runnable for the moment.

As noted by others i think, piston to crank clearance was basically nothing. Just beveled the inside corner of piston skirt about halfway and that gave comfortable clarence.

Skipping forward a ways, had to trim a bit off the fuel line to keep it from kinking.


Everything else went together pretty well, so we end up with this.

Once again, as others have noted, chain break mechanism is a little clunky, chain tensioner is a little rough, though it seems to get better after a few uses. Switch shaft action is rough as well, but all is functional. Had to tweak metering height lever to correct some pretty severe flooding, forgot the o-ring under oil pump outlet as well. Once that was all done, it starts, runs, idles and oils well.

Ditched the cheesy deflector in favor of some @Red97 action. Unbaffled the muffler and enlarged the opening under the deflector, left the opening in muff cover alone. Paint job and welds are thankfully not well lit in these fotos.

When i pulled muffler to mod it, i noticed some pretty light vertical lines all around bore of the jug, guessin i didnt flush bottom end very well... good compression and starts and runs strong so far so not worried. It'll be comin back off soon anyway

Nice job Custer. Hopefully it's a runner!

Shoulda put more fuel in it i guess. Video done before muff mod.

So i tore the saw back down and used my degree wheel for the first time haha. After a few test runs, i came up with roughly 95 125 88. Also traced intake and exhaust on piston to give an idea of how much could be widened, also how much room cylinder could be lowered if need be.


First pic (marked @ tdc) shows (sort of) that the clutch side of the exhaust port could be widened a bit more than the fw side. As close as i could measure it looks like there may be as much as .100 taken off the base before freeporting so thats cool. Second shows where intake port lined up. Obviously sharpie marks left a little bit around the edges where the port edge actually is, but it got me in the neighborhood.
After some figurin' i marked up the areas i wanted to remove amd got after it. Just widening and squaring of the intake and exhaust at this point. Also spent a couple minutes w some 300 grit paper getting out the smears in the wall from me not flushing the bottom end properly.
Came in to rinse cylinder and recorded this

After some more figurin' and some consultation w/ @huskihl , the plan is to lower exhaust a touch, reduce blowdown, and probly end up addin some epoxy here and there.

Getting ready to cut the base. Does it look square? Sorry my belt sander is worn out.

 

[Time's Standing Stihl]

Lordy! You're supposed to cut the top for a 2 piece Custer! Smh...

To clarify, i meant a physically lower exhaust, working more toward 100 *.

Put back together after a little massaging of intake and exhaust ports, also first run since the muffler mod. Not a huge difference, but feels like it holds rpms a little better in the crust.
