Model T Ford Forum: Forum 2016: HOLLEY VAPORIZER--REBUILD OR REPLACE???
Top of pagePrevious messageNext messageBottom of page Link to this message  By Paul Sherman Tacoma WA on Monday, October 17, 2016 - 11:26 am:

I found a 1919 engine with a Holley Vaporizer Carburetor. I have seen both side of the issue of these carbs. cussed and discussed so don't need to hear much more of that.
Now I need to decide if I should rebuild or replace the vaporizer, so need a little help. If I replace it, do I need to also replace both the intake and exhaust manifolds, and if so what should I be looking for? And which replacement carb would be my best option?
Thank you, Paul in Tacoma

Yes; you need different intake and exhaust manifolds. Also a different or modified throttle linkage (which may cause you to pierce your block and valve cover too), choke/mixture controls and fuel feed pipe.
The NH carb is probably the obvious choice.
I'm keeping my Vaporizer, though if I had an NH, I'd keep that.

Paul a 1919 block will have the hole in the casting between # 2 & 3 cylinders and,depending on the age of your steering column, it might have the throttle linkage in the right location as well making it a fairly simple job to switch to an NH. Just make sure you get a good straight exhaust manifold, the intakes are not much of a problem. The repro exhaust manifolds are well worth the money.

I made this adapter to run an NH on a vaporizer manifold. No need to replace the manifolds.
Adapter

Putting a NH right at the Vaporizer intake manifold would mean the adapter could be a lot easier to make, though you would need a fuel pump too..

Here's from the clown car discussed in another post today, a '25-'26 NH on a Kingston Regenerator manifold:

Ken:

I have never seen one of those adapters. How difficult are they to find?

Jim, Ken wrote: "I made this adapter" so they can only be found as raw steel to be cut and welded into shape..

I sent my troublesome vaporizer to Russ Potter who worked his magic. Best carburetor ever on the T. Don't know what he did, but he did it right.

So what is a good working vaporiser going for these days?

I had to get the vaporizer off of my off of my 27 roadster and went to the NH. I bought a intake and exhaust manifold to make it work but it runs nice now.

Russ Potter is good.
