I think I know the answer to this one, and I don't
like it.
After 2 good days at Road America 3 weeks ago, I
started losing oil pressure and parked the race car
(1275 motor). The machine shop I've used for 4 or 5
years closed, I needed work fast and used a different
place. The motor came through OK, the crank needed the
rod journals turned .010, otherwise all OK. In the
interest of time (HA!), the shop assembled the short
block. The car wouldn't start. Everything looked
OK,the dizzy gear was in properly, TDC looked like TDC
on the crank damper marks, etc. I statically timed it.
The timing cover was on, so I can't see the gears, but
from #1 valve at least, the cam looked properly timed.
After consulting with Flounder and Peter, we figured
the dizzy was in 180 out. I swapped wires 1&4, 2&3, it
started immediately, and ran fine for break in (no
load on the motor). I carefully put the motor at TDC,
and pulled the dizzy gear. Huh, it still looks correct
(slot at 2 o'clok position, "large" half up). I assume
my eyes are playing tricks, I verify 100% that the
large side is up (which, BTW, is how I've assembled
that motor 2 or 3 times). Put it all back, still 180
out. It runs with wires swapped, but not when they are
as they should be. Triple check, at TDC the rotor is
pointing at #1 wire. The cap, wires, dizzy are the
same ones from 3 weeks ago, they have not been
touched.
So...is the cam installed 180 out, which I assume I
will find is a bad thing when the motor is under load?
Or doesn't it care? I think it will.
The car needs to be on the track this Friday, I'm sick
of this sh!t.
