Intermittent behaviour sounds like mobile dirt (eg chip of rubber from
reassembly of fuel hose), or something like the choke flap sticking.  Are
the choke flaps opening properly?

I got one good starter motor from 2 and got the crate up and running again,
Its had a problem in the past of not wanting to idle, and running roughly
down the road.
I rebuilt the carbs again last fall, made sure everything was perfect, all
the passages clear etc. but didn't have enough starter to get it going again
for long but It seemed to have the same problem.

This spring I got it running, adjusted and sync'd the carbs and it ran and
idled perfectly.  Drove it a couple miles, no  problem.  Now after having it
in and out of the garage a few times its back to the same problem, no idle,
will accelerate if pumped but not with the throttle just opened, sometimes
it would idle a bit on the left carb but nothing from the right.  I can
floor it sometimes and it will just bog down and very slowly recover.

What I know is right.
Has good fuel pressure
Carbs are all clear, or they were anyway.
It's a 65 with no idle cutoffs, so its not that.
Vacuum advance works properly, stock dizzy. good spark.
Adjusted and sync'd properly, as it was running and idling perfectly just a
couple weeks ago.

Im at a loss. had these things apart and found nothing, don't want to pull
them apart again as I cant get the gasket kits anylonger and it didn't solve
the problem anyway.

I HATE CARBS!  Woulda had this fixed if it were FI..  :-)


Any ideas??  

Keith
