Arrow Stromberg UC-3/4 Parts, Parts Diagram?

Evening all,

I'm rebuilding a Stromberg UC-3/4 from my Wisconsin AEH. It is an L45B2, Stromberg part number 426020A.

The Idle Tube is blocked solid - no matter what I try it won't pass any air nor fluid (was using alcohol and compressed air to test not gasoline). If I understand how this carb works correctly, no fuel from the idle tube = no fuel at idle.

The only way to get in there to clean it is to remove the Idle Tube and the Main Discharge Jet.

Here's the rub - I am rarely successful in removing similar parts off of Briggs carburetors. Thankfully, Briggs parts are pretty easy to find.

So, before I take the thing apart, and possibly damage these pieces, I want to make sure I can get new ones.

Here's the other rub - the only parts list I can find is in a Wisconsin Carburetor manual, and while it lists the parts, it does NOT list part numbers for the UC carb.

So! Anyone have a good parts number listing for a UC carburetor and/or know of a good source that would have an Idle Tube and a Main Discharge Jet for the same?

thanks much,
ben

Morning all,

An update - I sent an e-mail over to site sponsor McDonald Carb and Ignition. In less than two hours, I got a reply back from them indicating that they could supply both the main jet and the idle tube.

I was extremely happy!

thanks much,
ben
