Carbs ejecting fuel

[nate6472]

I have a 3.5L carb and there are 2 lines going from each carb to the left side of the frame. The engine had been sitting for 3 months and when I fired it up it was fine. The 2nd time, the fuel started ejecting. What is this all about? Any help is greatly appreciated. Thanks

Have to be a little more specific. Hard to tell what you mean sitting here a few hundred miles away. It does sound (If I guess right) that there is a problem with the fuel return lines. My two older cars had this side draught system on their 3.5L engines, now they both have American 4bbl's.

There is a single line connected to each carb which are open at the end, attached to the frame behind the front wheel. Fuel dumps from these lines while idling and I assume if driving. It is a steady stream. Been researching it and it could be a float problem. Where can I get info on converting to American carbs?

It's pretty easy to convert. I have used both Offenhauser and Edlebrock 4bbl manifolds (I like the Edle better), both with Edlebrock 500cfm carbs, with electric choke. These manifolds are listed for the 215cid Buick engines and sometimes have a notation that they can be used on Rover V-8's. I just rerouted the control cable and fuel line to the single carb. Some folks use the Holley 390cfm carb which is closer to the proper size, but they are pricey. The only downside (?) is an increase in horsepower, and with good tuning mileage won't be decreased very much if at all.

Thanks. Did some googling and came up with edelbrock 215 for manifold and 1404 for carb with new pricing of $239 and $304 respectively. Is this a DIY with a shop fine tuning? I am mechanically inclined (rebuilding door guts now). Thanks again !

DIY, fairly easy to tune as different dip rods and jets are available from hotrod shops and on line. Do an Ebay look about you may find bargains on these items. Pretty straight forward American manifold installation.
