Tubs, good observation on the advance lever moving. I have a string
of dimples drilled, and am using a spring and steel ball for a detent.
I loosened up the pressure on the detent previously so it was easier
to get out of design range on the timer. Guess I better try to snug it
back up. Every time I’ve got it started and advanced the timing,
to near TDC it has died on me. Every time I’ve kept my hands
off the timer, it’s died.

I cranked on it more last evening, experimenting, starting with the
fuel needle while it was shut off. It would not fire, so I’m hopefully that the needle
seats shut. I squirted some gas in the plug hole and tried again,
and it did fire. I keep tweaking the needle open a little at a time,
trying to get it to fire, and if it didn’t, I squirted gas in the plug hole,
to see if it would “catch”. I finally got to a point on the needle,
I think about 1/4 turn open, where it would fire without squirting
gas in the cylinder.
A few times I was hopeful that it would keep running, but it wasn’t to be.
If I opened the fuel valve any further, it wasn’t happy, and I had enough
of cranking.

Also last evening I made a 1/2″ pipe adapter for my compression gauge,
out of a 1/2″ pipe nipple and a 2″ 14mm extension that came with my gauge,
that I never used. Reamed the inside of the nipple out a tad, and inserted
the extension with some thread locker. If it’s cured this morning, I’ll
see what kind of compression I’m working with.

Prepare to be boarded!
