Help-4bbl dumping extra gas

[PKRWUD]

Kaspar-

I got your message, but didn't have a number to call you at. Since the problem isn't occuring at the primaries, I doubt it's pressure related. It sounds like a textbook example of having the float adjusted wrong for the secondaries. If adjusting it doesn't work, then remove the needle and seat and inspect the O-ring for nicks or tears. Replace as needed.

Odds are you just need to lower your float in the secondaries:

1) Remove the secondary sight plug in the side of the secondary bowl. Fuel will spill out, so have towels ready.
2) Back off the large flathead, adjusting nut lock-screw on top of the bowl, and turn the 5/8" nut underneath it clockwise 3 complete turns.
3) Tighten the lock-screw.
4) Start the engine, and see if fuel starts to flow out of the sight plug hole. If it does, go back to step 2 and repeat. If it doesn't, losen the lock-screw, and turn the 5/8" nut underneath it slowly until the fuel just barely starts to trickle out of the hole.
5) Tighten the lock-screw.
6) Shut off the engine.
7) Replace the sight plug, making sure the gasket is still in place.
8) Soak up any spilled gasoline.
9) Fire the engine, and verify that the problem has gone away.

Note:
Be forewarned that anytime you losen the lock-screw while the engine is running, fuel will spray out from underneath it. This is normal.

Take care,
