Dont use starting fluid.I own a lawn and garden bussiness with alot of two
cycle stuff.We always use WD40 for a start fluid.it is oil based and wont
hurt the motor at all just will be smoky.
Did you time the rotary valve?

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?

Is ether being used for starting fluid? If so you
my be running several
revolutions on the ether and then starving for fuel
because it is not
being supplied from the pump.
Batteries can fail (ground out internally) from our
engines vibrations
over time causing the electric fuel pump to
quit....the vibrations stop
and the battery works again.
Vacuum pumps can fail because of a failed pump
diaphragm...there can be
a 'catastrophic' diaphragm failure where nothing
gets pumped, or there
can be a maddening chaffed diaphragm where the
vacuum from the crankcase
that operates the pump draws fuel through the
diaphragm and floods the
crankcase.
I takes 3 things to make the engine run....Fuel, air
and a properly
timed spark.

Hello all!!
Thanks again for all of the ideas on re-firing the
motor.
Out of semi-desperation, I installed 2 brand new
carbs on the motor. It
seems to have helped, but it's still not starting
and running. It's more
consistent about firing through 2 or 3 revolutions
before it stops.
Different throttle settings and different idle air
mixture settings
don't seem to help or hurt much.
Has anyone seen a similar situation?
