Piston position is irrelevant as the pressure will equalize rather quickly around the rings. Also as part of the vacuum and pressure test you should push/pull and rotate the crank as this may show marginal sealing/leaks that only appear when the crank is in a certain position. In fact, one test to check for leaking seals is to turn the saw up / down / and sideways to see if the idle rpm changes.
Did it go back higher when rotating the flywheel back?
It depended on how fast I moved the flywheel. If I did it with any speed (pulling somewhat slowly on the pull rope), the vacuum level would raise and lower as you would expect, but then always return to a little more than 7 in hg. If I moved it slowly (just moving it with my finger), the value would fluctuate slightly but again always return to 7 in hg. If I ran it up to 14 in hg, and them moved the flywheel until it started to bleed down, and then ran the vacuum back up to 14, it would still blead down to 7 without moving the flywheel any.
Like I said, put grease heavily in the inner lips and see what changes. Change them and be done with it.
The seals will come with the complete gasket set for less than just the seals alone. The IPL should give you gasket set part number.
Complete cost for an OEM gasket set from my dealer was $13.49. Total cost for both bearings was under $22. They should get here on Monday.
No. I have a co-worker who works on 2 cycles as a hobby who has the tools and substantially more experience doing it than me (which is zero). He's offered to do my 036 as well as my 064 for me.
If vacuum, in/hg, isn't given, you need to double the psi to get proper vacuum number. The conversion is approximately double the psi. So, 7psi = 14 in/hg. Yes, vacuum First!
