Technical So let's discuss Stromberg 97's and associated parts

First, let me preface this with, I am not a carb guy. Wanna talk Hilborn fuel injection, I'm all about that.

So, I have a little 29 Model A roadster with a 265 and a 3x2 with 3 Strombergs. The previous owner only had the center carb hooked up. I found the linkage under the seat for the other 2. So basically it's a 2 barrel.

The problem: It pukes all over itself occasionally. Like out of the top, around the accelerator pump rod etc. The car has a really small 12V elec. pump and one of the Mr Gasket regulators. I figure the float is hanging and allowing it to overfill.

The questions:
1. Who sells the best/most complete overhaul kit for a 97?
2. Who sells the most accurate low pressure regulator 5 lbs. and under?

I would like to get this thing running right, but I only wanna do it once.

Thanks,

Root

 

I use ONLY a vein type pump. If its a pulsating pump it will push past the needle and seat. I also set the fuel regulator at 2-3 PSI

 

Holley 12-804 is the regulator we use for low pressure applications Root.

 

Holley 12-804 regulator. 1-4 psi. Personally, I avoid the round dial types.

 

Buy one of the Holley regulators. They come in a higher pressure version and one that regulates from 1 to 4 pounds. And buy a low pressure gauge from ****ster here in the HAMB cl***ifieds. Then set them to 2 pounds MAX.

And, any Stromberg parts or service you need can be obtained from our own Uncle Max. He's the absolute best.

 

Dont buy the round Holley. Its just a restrictor and my engine was starving at 90

 

90? Dang son......slow down and smell the roses.

 

****ster here in the Hamb will provide you good rebuild parts.
Residual electric pump pressure after the engine is shut off will cause Stromberg leakage also. A solution would be to install a separate switch for the pump and turn it off before the ignition.

 

It does it going down the road. I can always tell. It smells like raw fuel and then I can look over the windshield and watch it geyser. The round Mr. Gasket regulator worked great for a while.

 

Probably the best regulator is this one. Aeromotive 1-5 psi.
I installed one on my RPU with the 3 new Strombergs from Clive.

Wow, great attention to detail.

 

Blue, that's a sanitary looking installation. Is that regulator aluminum? If it is I think I'd be inclined to scratch the Edmunds logo into it and give it a buffing. Help hide the newness.

 

Thanks, I welded a mount for it to the edge of the crank case draft hole block off plate.

It is aluminum and I had considered taking it apart and blasting it for black paint but never got there.
I may in the future but I think it looks okay down low on the side of the engine.

And it works great at 1.5 psi.

 

Oh, they are spendy though. I could buy six of the good Holley regulators for that price.

 

I’ve heard that they aren’t so good anymore.

 

I just run the stock flathead pump, works great.

On another note, what can I use to get a nice looking finish, without resorting to paint.

 

I can't on a SBC. I mean I guess I could, but it may take some ciphering.

 

I did some troubleshooting tonight. When it would start loading up, I would turn the pump off to see if it would clean up and it did. So the carb may just need a new pressure regulator first, then worry about the overhaul later.

 

I run one of these Malp***i units on my car with 97’s. It is a low pressure regulator and filter all in one.

 

Anything stromberg related shoot uncle max an email, he is great to deal with.

 

Pretty Y-block!
