BTW: What do I do with the needle valve once I find it?

treat it very carefully so that it doesn't bend.
The old pump probably belched a bunch of dirt into the carbs which is causing the gas inlet valve (which are hooked up to the float) to stick open and overflow. I believe that you have Stromberg carbs so....
To solve this problem: Take the carbs off, take the bottom cover off there are 4 screws which hold it on. The bottoms should come off easily. The big thing that flaps up and down is the float. It controls the little valve which lets the gas in. Make sure that the float moves smoothly (freely) and that the valve closes when the float rises. If there are bits of old pump in there, the valve may be sticking open and causing the flood. Just be careful no to bend anything. The gas volume in the lower portion of the carb is controlled by the hight / angle of the float, and if you bend the needle valve then it will leak, and flood.
Once it is clean, put it back together and go for a victory drive.

hello Alana,

"if you made it bigger then you'll get more flow right up until the pump maxes out."

I'm afraid that I have to correct you here, that is just not true. The lines are capable of a greater flow rate but the carburettor, in this case, determines the flow so bigger lines will not be a factor.

You are absolutely right, and in the cold light of dawn I see that /bcforum/images/%%GRAEMLIN_URL%%/wink.gif - but there is one caveat. If the fuel pump puts out a higher pressure than the carbs are prepared to regulate then the flow rate is determined by the line size and fuel pump.

The results are unfortunate - in my case, when I went to a 'low' pressure electric pump (that wasn't perhaps as low as it might have been) it meant that petrol spewed out of all three carbs and went all over the place...

From what Tinster is saying though, it sounds like he had the same problem with the carbs on the old fuel system. Since he paid all that $ to get them rebuilt, I reckon he ought to be thinking about sending them back.

edit: or as was added since i started typing this - fix it himself. good luck either way...
 
Re: Crypt Update

Well, I've never been one who is afraid to make decisions
or to take risks.

I pulled the carb apart. I can always send off the pieces
to Jeff to rebuild it for the second time. Then again,
maybe I can put it back together.

These carbs have like 225 miles on them from Jeff Palya
refurbish. I noted some black silt in bottom of float bowl.
Floats clean as a whistle. Inside of carbs sparkling clean.
Needle clean and straight. Floats rotate easily. No debris
of any kind visible. I ran thin wire into the blind openings.


I guess, I'll put things together and see what happens.

MEMO TO TINSTER:

GET RID OF SIX GALLONS OF GAS BEFORE WE END UP READING ABOUT YOU IN NEWSPAPER OR SEEING YOUR STORY ON CNN.
 
Re: Crypt Update

Would a fuel pressure regulator between the pump and the carbs be worth a try?

Easy to do/undo and cheap. If there is too much fuel flow might that take care of it without having to replace anything else?
 
Re: Crypt Update

All Knowing One , please Sir-
How does one rid oneself of 6 gallons of
contaminated gasoline?

In high school we'd have dumped it over a bridge, thrown a match pack and enjoyed the brief inferno that flowed down
the Susquehanna river..

Re: Crypt Update

dale, hey sorry if this seems just stupid, but did you attach the new fuel line to the carb vent instead of the fuel inlet on the carb? you should not need a pressure regulator and if there is still a problem check the fuel needle and seat that is under the fuel float. that may be sticking

Good, that is crud from you old fuel pump hoses ..... almost definitely what had the fuel valve stuck open.
Good work!
