When I arrived home from work at 4:30, doc's care package had arrived. I wasted no time...
Those are where mine wound up after all the molesting... I measured everything I had in the interest of keeping good track. Disassembled, cleaned base mate, installed doc's piston with no ring, snuggled the jug with two bolts, and measured everything. The squish was perfect at .018". I documented the new numbers but I won't be posting them as requested. I did however say I was going to take pictures, but like a child on Christmas morning, I did not. All I can tell you is that I saw what he did and it was delicate, symmetrical, clean... Exh port is shorter, yet wider than mine. Nice subtle notches on the outer floor. The lowers appear untouched. The intake got alot of attention. And the uppers as well. So I assembled. I discovered the pin clips from the hiway kit don't fit the oem pistons. So be mindful of that if swapping around. It's possible to get the clips to appear installed. One of those pops out and it's likely the end of the whole unit. The other discory I made was that to get these things in the ballpark, the cylinder has to be lowered so much that the exhaust needs the bolt holes altered. Lots of meat off the base. Easy fix, port matched the gasket and muffler... I'm also considering finding a slightly longer stud for the top engine cover, and possibly a shim for the rubber bumper that goes on the other one.
@drf256 had also sent me a nice metal screen filter, but I haven't put that on as my 426b carb has that vent nipple with oring that goes into my current airfilter. I figure that discovery has been made by many on here, so I'm sure there's a mod, or, a better carb I should be running. Regardless, put it all together, pulled twice with switch off, choked, and pulled once and it was immediately alive. I did the base carb tuning. Tomorrow morning when I get to work, I'll see if I can get a video of it cutting. It sounds RIGHT!
