John --
Too far for me to drive, otherwise I'd be over shortly ... but I'll
share what I've been told about such problems: 90% of carburetor
problems are electrical.
Is the car timed right? Do you have spark at all four plugs? Are
the plugs gapped properly? Are the plugs firing in the correct
order? Is the engine ground strap in good shape? How do the rotor
and dist. cap contacts look?
And for the mechanical -- are the valves adjusted right?
And for the fuel/air -- is the float set at the correct height? Is
the fuel filter clogged? Is the pump pumping? Is the air filter
clean? Is the choke operating properly (i.e. it's off when you want
it to be off)?
I know a lot of it's obvious -- but sometimes we all need to be reminded!
HTH,
