Ken Uhrick is probably spot-on when he says that the vehicle isn't getting
enough fuel. What you've got to ask is "Why?". It could be a multitude of
reasons but here's a few to check:-
1. Take off the fuel feed pipe at the carb. put the end of the pipe into a
plastic soda bottle, then get someone to switch on the ignition. Does the
fuel gush out into the bottle? Plenty? If not, could be blocked/constricted
fuel lines, filter, or faulty in-tank pump.
2. When the engine is cold, take off the ignition lead from one plug. Tape
the lead out of the way so it won't arc on everything. Crank the engine as if
you were intending to start it (use choke as necessary). Then if it fails to
start, remove the spark plug immediately and check to see if it is "wet" with
fuel. If it isn't wet, then check out the operation of the choke mechanism to
see if it is working.
3. If fuel is reaching the carb but does not seem to be getting to the
cylinders, it could be a blocked carb (swap): it could be an air leak at the
manifold or, as one of our List mutt-owners recently discovered, a
cracked/leaking vent-valve: or it could be due to low engine compression
(check with a compression gauge).
4. If the plugs ARE receiving fuel, then it is most likely incorrect ignition
timing, faulty points/condenser or coil. Are you are getting a good spark at
the plug-end?
5. As an outside possibility, if your A1 still has its low-oil-pressure
switch fitted, check it out as per the TM, it could be faulty.
When you DO find out what the problem is (and you will !!!), please share the
solution with all of us on the List.
Seasons greetings.
