A puzzlement:
Car won't start. Good spark, points correct, strong starter, plugs and wires good. Strong fuel flow from pump to carb bowl. All carb jets cleaned, fuel bowl clean and no sediment.
Crank the engine, not a single plug fires.
Dump gas into carb throat, takes about five seconds of cranking to get it to fire - then it runs a bit but stops (like it just runs out of gas). Open carb top, the fuel bowl is full. Once it does run with a prime, engine runs strong and smooth ... then just dies.
Engine was hard to start since I got the car two weeks ago. Now that I cleaned the jets (!) it's worse.
Pump the gas pedal, linkage moves, accelerator pump works, butterflies open - but no go. When the engine runs after priming, pushing gas pedal does *not* increase engine speed. Instead, pushing gas pedal seems to "flood" the carb and kill the engine.
I *did* notice that fuel weeps from the gasket that joins the carb top to the carb base, and fills the pan under the carb. Would that be enough to prevent gas from getting to the manifold? Note: the gasket is the "insulation flange" between carb top and carb base - NOT the gasket between base and manifold.
