Ok... got an updated report and a pic.
The pic is more useful than the report.
And it's not revealing any real secrets...
We've seen this theme before, in the generator cleanup thread. I'm not gonna get all excited this time around, the novelty of it has worn off.
The report:
The plug hole is much smaller than I remember it, and without a camera, I'm simply not going to see the edge of the crown and the wall in the same frame of reference... not for lack of trying... I even thought I was being clever by trying a laser pointer as the light source. Turns out, the white LED right next to it is still more suitable, but that's all for naught.
The crank simply doesn't have enough throw to get the piston out of the way far enough.
The PCV:
The "good" news - It's not completely blocked...
The bad news - My oral cavity isn't calibrated in mbar, atm, psi, kPa, or any other scale one might find air pressure and lack thereof listed in.
The "not-as-bad" news - I tried it but I didn't inhale
So I still basically don't have a whole lot to go on. I made sure to cycle the crank thru all 4 strokes and then some, a quarter turn or so at a time; no perceivable difference.
The only thing I can say for certain at this moment in time is that there's no gas in the crankcase, but it still tastes like $#!+.
I can't get to the PCV retainer bolts despite it being right there in front of my face... something about a plastic cooling duct and laws of physics, I can't recall exactly.
So, where does this possibly stand... From what I *could* work out, the carbon is highly irratic on the crown, but off to the one side I could see clearest, it *seems* like it may even be thicker near the wall? I really don't know what to make of it, and an eyeball I had "full usable 3D control" over was difficult enough to make sense out of anything... forget it with a once again temperamental phone camera.
This was taken the other day while I was up at the auto parts store and had replaced the majority of the [then missing] oil with the last combination that was known to be ok... which didn't work, and neither did adding "stabilizer goo".
The special fx are courtesy of good old fashioned frame rate slip.
Okie... ideas? LOL
