Holley 4175
Good afternoon everyone, sorry for my English ... is a translator, if any of you have can help me with some questions of my carburetor, it is a holley 4175 650 CJM.
The problem is that sometimes the gas is full and falls out of the carburetor by one of the deposits.
Another issue I have is if this carburetor can give you a fuel line .. like this http://i116.photobucket.com/albums/o13/682XLR8/68% 20Corvette/IMG_0056.jpg
Best Regards and Thanks

Get back on these questions. Most likely the float in the side that is dumping fuel is too high. Reference the Holley.com web site and under their tech articles there are procedures to set the float level and I believe a video also.

Gasoline comes from one of the deposits, the primary I think it is .. I bought a carburetor repair kit to have if changing all get together to fix the carburetor.
From us about fuel lines, do you know if possible?
Thanks

I think you mean fuel is dripping from the primary boosters onto the primary butterflys?? Is this right?
I would still ck and set your float level. With the engine running, remove the float sight plug and see if fuel is just starting to drip out of the hole. If it is running out , shut off the engine, loosen the nut and adjust CCW to raise the float level. Turn it about 1/4th turn and restart, check fuel level. BE CAREFUL AND HAVE RAGS BELOW THE FLOART BOWL TO SOAK UP FUEL. If it still flows after adjustment, you may have a bad needle and seat and a cleaning and kit would help out. The 4175 is a Q-Jet replacement with vacuum secondaries. Suggest you get a book on Holley carb rebuilding by say Clymer or Hayes to take you thru adjustments and rebuiding.
