Dellorto problem. disaster averted, garage reeks of fuel Options

[rhodyguy]

all set, ready for fire up, energize the pump (didn't spin the engine) and the pump doesn't quiet down (cb carb pump) as the bowls fill as it did with the webers. i look over and there's a thin fountain the coming up and fuel welling thru the square in between the main stacks on the dr side carb. puddles on top of both of the throttle plates.

the pass side has the duel banjo fitting. fuel supply line connects to one fitting and the other fitting is supposed to supply the dr side eliminating the need for a 'T". does it make any dif which fitting gets the pump supply and which one connects to the dr side carb? top fitting as opposed to bottom. the dellorto book mentions the dual banjo but doesn't specify if it makes a dif where the lines are/how hooked up.

i had just changed out the oil so i know the 3 1/2 quarts of BP will get dumped. any ideas?

This happened to me twice when my float valves would get stuck open.

Usually when assembling the carb they get hung up somehow and can't close.

I was lucky because I noticed it to before firing the ignition.

Always check for this when you have had the float plate off the carb.
