Hey Dan&Rambo, and Mars-questions:

jjbubaboy

Been researching some carb spacers for my 36T because I am still getting fuel too warm (hot) really! On longer runs.

Found the post from 11/07 about the Delco spacers #3692799, so now the questions.

1) Will these work/fit for a WA1 carb?

2) How thick are they and use one or 2?

3) Any idea on gasket numbers and I presume 3 needed for: below, between, and on top of them ?

Thanks again!

(And also if anyone else has any valued feedback!)

I use 8 spacers on my 1937 (2 bbl.) carb; 4 above, and 4 below the metal heat deflector. As I recally, I had to install new, longer threaded studs to accomplish this.

I haven't used mine yet. They're about 1/2" thick made of a baklite material - typical for carb spacers.

My assumption is that you install these between the manifold mating surface and the cast iron base of the wa-1 carb.

Putting this between the carb mating surface and the cast iron base would increase the distance to the throttle butterfly - unsure of the performance issues with trying this mounting style.




This would be my guess-timate as to the application (not to scale )

Hey Dan,

That looks perfectly like what I was thinking. I want the baklite type to try to keep the heat saturation down. I have some kind of spacer in there now but its a metal type and seems to run good otherwise.

Thanks!

Hey Jon,

What are you using for spacers?? That sounds like a lot and how does that effect any performance?

I've always run a carb spacer on a carb'd performance optioned engine.

I know a lot of folks run a stainless heat sheild - to be honest I think I'm going to make some out of aluminum. Stainless is more like a heat catcher and the heat takes a long time to dissapate from stainless steel.

I think a lot of folks run gasket stacks in place of the baklite spacer.
I'm not sure why - other than not knowing the spacers are available?

Gasket stacks would just be more places for vacuum leaks IMO.

So, are the Delco spacers still available?



Also, I like the idea of aluminum spacers! Think I'll make me a set.

I bought mine on ebay but I know Ken Cates has Delco 3692799 listed as a valid parts number as well.

This guy in Washington has them listed on his Engine Parts page.

If he stocks them, there should still be a source out there.

After doing a search with the Part #, your link appears to be the best place (only place advertised?) to go.



I had forgotten about this old link:

I was thinking of NAPA, or maybe even calling Hagens

Re the bakelite spacers. Does anyone know of and recommend an easy to find alternative material to bakelite so that I could make my own? Perhaps something that is thick to reduce the chance of leaks as mentioned. Regards, Barry

Hey Dan,

went by Napa today and they couldnt pull anything up or cross the number. Being a holiday weekend probably didnt help much either!

I wasn't aware of the bakelite spacer (for 1937, at least), just the standard gaskets (about 1/16" thick). As I said, I used about eight of them, which was NOT a factory procedure, since the threaded studs (holding the carb to the manifold) were not long enough to fit all eight onto the manifold. (I put in longer studs.)



The metal heat deflector was not standard in '37 (nor in '36) as far as I know.



I looked in the 1937 parts book and did not find a bakelite spacer. I have just got off the phone with "Mister '37", Robbie Williams, and HE had never heard of such a spacer for the '37.



So, it's possible that you have a '36 factory spacer. Interesting, I had never heard of such a thing.

Here is supplier (Chevs of the 40's) of the Delco 3692799 for '50 to '59 235 cid Chevy. They also have Delco 3692797 which is similar but for the '34 to '53 Chevy.

That's reasonable, but will they fit the Carters? If so, I'm going to order a couple.

Well, I believe they do. People that have a Delco spacer have tried it I hope. Also Chevrolet sometimes used Carter W-1 carburetors.

Hey all,

Since I cant seem to locate anything local (didnt try Hagens though) I am going to order one from Chevs of the 40's and see what happens.

If it fits then YEE HA!

Guess since I dont have gasket numbers I will just try to get those as well.

Rest assured, the Delco ones I have fit the bolt pattern perfectly.

The center looks good as well, no clearance issues.

On the delco style one side is flat the other has a relief and is bezeled.

The carb base gaskets for the same chevy carbs should be a match as well, or any WA1 base gasket for that matter.

My camera batteries are on the charger I can take some pictures of the WA1 base mated up to the spacer later if you'd like.

mars55

As far as gaskets go. NAPA lists three different numbers for a '48 Chevy.



9520 W/O Governor



8812 W/ Governor



9066 Carburetor to Governor

"Fits like a glove"

Hey,

Great pics Dan!

And Mars has the numbers correct. The difference is in the bolt hole spacing.

The 3692799 one has 3" spacing and the 3692797 is 2 3/4 which is what my 36 is.

Going to give that one a whirl and see what happens.

THANKS!

In the For What It's Worth department, I've been using spacers that I made from Ultem plastic for both my carburetors and fuel pump, and have had no problems whatsoever. In several years, no leaks have developed at all, and I drive my car regularly.

As well as spacers, you would do well to make up a heat deflector to shield the carburettor bowl from the manifold heat. This can be made out of body steel, and sandwiched between two of the spacers, and extend along so that a good air flow from the fan blows back over the carby withoug picking up manifold heat.

jjbubaboy

Hey,

got my spacer and gaskets today from Chevs of the 40's. Looks great and fits perfect. Will try to post a pic of it. Will see how it works next!

And Geoff, I already modified a twin H heat shield and added that and it helped a little but just too much heat coming up due to the design I guess and the carb just soaking it up!

Thanks tho,

T Jeff
