Make sure your rotary valve is turning. As stupid as it may sound, if the
rotary valve is placed just right, that thing will run on one side (barely).
The rotary valve sits on the end of an auxiliary shaft that also runs the
oil and water pumps. A steel gear on the crank drives a brass gear on the
aux. shaft.
Have you tried swapping ignition pieces (coil & CD)?
Have you swapped fuel filters? For the purposes of troubleshooting, remove
the filter altogether.
Have you tried other carbs? Plugs? Gas? (Try running fresh gas straight
out of a jug and into the carbs)
Have you tried bribing Cory McLeod into driving down from Memphis to look at
it? Or you up there?

Hello all!!
Well, a new fuel pump didn't magically remedy the
situation. Like before, some starter fluid will get it
to run like it's firing every other revolution for
about 10 seconds before it dies again. What's the best
way to dry out an engine that is suspected of being
badly flooded?
Does its attempt to run for at least a few seconds
tell us anything about the ignition and rotary valve
timing, good, bad or indifferent?
Thanks in advance for any and all assistance,

Chuck,
I'm saving starting fluid for an absolute, drop
dead, last resort. I have a
can, but haven't used it yet.
The motor has a vacuum fuel pump. I'm getting fuel
to the carbs. Would a
chafed diaphragm fill the carb float bowls AND flood
the crankcase through
the pulse port?
Kenneth
