32/36 to 38/38

[Anonymous]

Okay. I'm thinking about ditching my (crap) 32/36 Holley/Weber carb and replacing it with a new Weber 38/38.

I currently have my 32/36 mounted to the intake with one of Tom Langdon's adapters. I drilled out some extra material to make the carb sit with the proper orientation. Looking at the firewall, the electric choke sits on the driver side with the cable throttle linkage at the ear. I went to a nice stainless cable setup a while back.

I know that the HW 32/36 is sold either as a DFE or DGE, one of which is a mirror of the other. I think mine is the DFE. I noticed that the Weber 38/38 is a DGE.

This raises two questions: can I use my current stovebolt carb adapter for the 38, and will it keep the same orientation? I don't have the original throttle linkage anymore and I like my cable. Plus, I'm a little worried about what happens when the carb is incorrectly situated. If the carb is not orientated the way it is now, it dies when I take left turns.

As you've found in current setup, the results are specific to the combination of - modified- parts already installed, the only info of much use will come from your trials.

With a litlle finesse and some grinding you can get any carb to FIT. Adaptors are "adaptable" Getting it to WORK on your engine is the fun.

PS Where'd ya get the "nice stainless cable" ?.
Need one for new multi carb attempt on a built 250:

HI,
I have the 38 on a stovebolt adapter, so it will fit. I am also confident that it will fit with the same orientation as your current carb, and that you will be able to use the same linkage and fuel line setup.

I have the floats on one side and yes, it dies on left turns. Sounds like you solved that problem.

Now there's a man who is not afraid to do some experimentation...

Should be fine. I replaced my Weber 32/36 (electric choke) with a Weber 38 (electric choke) and it was a direct swap. Unbolt one, bolt on the other. I was using the Clifford adapter, but I doubt that would make any difference. Orientation is orientation. I didn't change adapters between carbs.

With that out of the way, I can tell you how much nicer the 38 is than the 32/36. It is a better carb across the board... Better performance, simpler design...heck it even sounds better (deeper sound when WOT). Not to mention I think the 32/36 is a bit small on our engines anyway.

I splurged on a Lokar Eliminator pedal and matching cable. I found an engine mount for the cable at the junkyard from a Maverick. Works stellar. My only complaint is that I have small feet and the cable setup has more travel. But I like the idea that in order to floor it, I really have to make that decision.

Good news about the Weber 38. I'm inclined to pick one up. Any tips on jetting?

Mine came jetted for a jeep. It ran pretty well out of the box, but I had to increase the idle jets one size. Currently as follows:

idle jets...55
air corrector...185
main...142 (this seems small to me?)
accelerator pump nozzle...70

This setup works quite well, although I think it's a wee bit rich all around based on plug readings and smell and the fact that i get horrible mileage (13mpg). That last part may be due to my float level being too high, which I suspect, but haven't confirmed, yet.

Thanks. I'm saving up to buy the carb even now. I'll be ready to go a in a week or two. 13mpg? Really? Crap. How do you know where to adjust the float level to?

My buddy owns Top End Performance and has been selling and tuning webers for decades. Here is one of his websites with plenty of tech info including float level adjustment.

I've never done any carb tuning of any kind, except for replacing that idle jet and setting lean best idle. I've got the whole thing apart right now as I am swapping heads. I think the 13mpg thing is a fluke and will be remedied with proper tuning.

i have a weber 38 that i bought awhile ago. i have not installed it yet. not sure if i will use it or a holley 350 i have too. i noticed that your friends website is in north hollywood, very close to me. so he really knows webers huh?

Yep, he knows webers. His name is Steve Nelson. I've seen all sorts of ill running cars with weber conversion come in his shop and leave running great. Plus they do great fabrication work there and they are very handy with carb linkages.

Just don't let him see your car, though. He has a passion for 400hp turbo supra engines and has been dying to put one in a '63 falcon convertible...

Thanks for the information, it will be good to keep on hand for future reference.

400hp engine huh? I might even let him put a supra engine in for that kind of performance, wouldn't that be a kick in the pants!
