Good observation on the filter drying up.

Fuel pumps go bad just like people go bad. Sometimes people dont wait 20 minutes though.

Mechanical pumps are cheap to replace and one that pumps a higher volume may be the way to go. A stock replacement will probibly do though, in your application.

Pay close attention when installing the new one. The arm on the pump meets a lobe on the front of the camshaft. The lobe pushes down on the arm to pump fuel to the motor. A slight resistance should be felt when sliding the arm into and under the lobe. (Not a big deal doing this.)

While the pump is off I like to blow air back towards the tank to clear the line. Somtimes with old cars, crap clogs the lines up. Ive used a 12volt tire pump if a compressor cannot be had, works just the same. *Losen gas cap.

Re-adjusting your carb would'nt hurt either.
