After crying in my beer I went back and like you said, started from scratch,
and eventually got the engine running. Whooopie!! I don't know why there was
little compression in number 1, and why it was sucking through the exhaust
on intake, but everything seemed to clear itself out by trying over and
again to get it started. The one thing that was out of whack was that the PO
had marked TDC on the fan pulley 180 degrees out, and I used that for
setting up initial timing. It was only after carefully watching the rockers
and valves as my son rotated the engine through it's cycles that I realised
the error. When I found the little (unpainted) nick for TDC, I found I had
set it up at 9 degrees after TDC. Using an ohmmeter on the points, I set it
up for 7 degrees BTDC. A little cranking later and it roared to life (by
then it was also flooded) a few farts and lots of smoke and it settled down
to a sweet-running engine, much smoother than before the rebuild; you really
couldn't tell the engine was running by looking at it. Been driving the van
all day and it starts with the barest touch of the starter. It's great
having the rig on the road again.
