Our 81 air-cooled has had a very slight intermittent
bucking for some time.  On longer trips it might give
one slight little hesitation but recover right away
and drive fine for weeks.

Last night it started to really buck...I would push
the clutch in, give a little more gas, and it seemed
to recover.  Finally, after one large buck, it stalled
and wouldn't start back up.  I ended up pushing
(luckily it was only .25 miles and fairly flat) it
home.

Checked for sparks and fuel pressure before it got
dark and both looked good.  Grounds are all clean.
Pulled the plugs and they looked dry...shouldn't they
at least have been moist after a bunch of cranking but
no starting?  Maybe the injectors are not being told
to open by the brain box?  Any ideas on where to check
next or what could be the cause?

Thanks.
marc
