I wonder why the guy would want to sell his double setup if it worked well for him.

I need to see a video of that leaking, I can't think of any brass rod that would cause leakage of that sort. OH, and some of the reasons someone might want to sell the dual carb setup is it won't fit with fenton headers, (I had to get a FENTON intake, the edelbrock wouldn't fit), maybe they got a wayne 12 port and it won't fit that either, he went with a V8, had clearance issues with the fender braces, simply changed his mind. There doesn't need to be an ulterior motive, no one mentioned whether it worked well for the fella or not, as a matter of fact, it didn't say whether it has even been installed on an engine period

A progressive two barrel will not work on its own, you need two of them. One is just to small for the 235. This is why they work so good in dual setups.

Unless the the carb has a direct hole in the casting letting fuel out, it can be rebuilt and made to run pretty decent. Any fuel running down the sides or out the shafts is from overflow or leaking gaskets.

First thing to do is add a small fuel filter right at the carb inlet. Then open the top and remove any trash that you see. Look under the needle valve and flush the area. Check the float for leaks and be sure it floats, replace it if in doubt.

Find another carb mechanic.

I agree with joe on all points, especially the part about finding another mechanic. The only thing I could add is you could learn to do this yourself, that way you know exactly what is going on. The rochester is about 1 step above a briggs and stratton in complexity.

There is at least one Holley-Weber carburetor (2300 or 5400?) that is a progressive 2-barrel carburetor that is big enough to not have to be used in pairs on 235 engines. Tom Langdon sells at least one type of these progressive 2-barrels ( 32/36 DGEV). Supposedly, these are 300 CFM carburetors. Two of these would be too much, even for a 261.

The Carter-Weber 740 (some call it a Holley-Weber 740 ?) is a much smaller progressive 2-barrel carburetor (used on 1600 cc Pintos, among others) and needs to be used in pairs on 235 engines. Tom Langdon sells these in pairs. Two of these are a little too small for a 261, but should work very well on a 235 (which is what Tom seems to usually recommend them for use on).

I agree with Brokenhead regarding trying to rebuild an original Rochester (unless it is leaking from a a pivot-shaft - that is not a simple parts-replacement rebuilt).

Looking at your beautiful truck so nicely done I'd make every effort to stay with a stock carb. My 53 was flooding really bad, gas everywhere, turned out to be way to much fuel pressure. Picked up an adjustable fuel reg. at Napa and now no flooding in the engine room. These carbs do not like pressure over about 2 lbs tops.

Interesting... I'll see if my guy mess. the fuel pressure ...

First, I'll have my guy test the fuel pressure. The guy I'm thinking of buying the set up from had it installed on a 235 which worked fine but he changed motors to a 261....too small for that. He's a mod here.

I may just do as many have suggested and have this Rochester repaired...Joe Hand has asked me to send it to him...would be nice, in a way, to keep it stock.. Lots of other projects to do in the mean time.
