Finally getting this mystery updraft carb ready for a trial. It's opening to the manifold is larger than the stock Ford carb and I hope it will be of some benefit. Still trying to find out the maker and any adjustment instructions if anyone out there has a similar piece.CarbLinkage

Neat setup. It looks similar to a U&J but definitely isn't. The intake looks like a U&J though.

The intake is quite different from a U&J. The float bowl looks like a Kingston.

Here's a U&J intake for comparison:

I looks like a Johnson to me. Hard to tell, so many of them look the same. A lot of carbs were sold with no maker name on them so the owner would go back to the dealer for carb cleaning, etc. Also, a lot of carbs were sold with a decal on the bowl with some name on it.

That manifold was sold by lots of places to mount "power" carbs on Model T's.

Here is a stock U & J. I have a new old stock U & J, thought I had some photos but couldn't find them. You can see the difference in the manifolds. The correct U & J does not have the boss to be drilled for a vacuum port.




Back to the shop, trying to get a Stromberg R-1 i the mail for a Maxwell in North Carolina and a couple Stromberg RF's out tomorrow. Busy Sunday.

Adjustment look straight forward. The spring loaded needle is air/fuel for idle and the adjustment on the back looks to be main jet adjustment. Try one turn on the first and 1 1/2 turns on the second to start. Set the idle so it doesn't burp or run rich. Then throttle the engine up to a high idle, open or close the main jet adjustment till the motor smooths out, then a bit more.
I know it might just be the bowl but it's looks a little like a Kingston to me.
