Questions and needs on carburetor.
-
[attachment=10410]DSCF0141.jpg[/attachment]
First off wondering what the function is for this piece on my Carter W1 carb is?
(the one in the center of the choke butterfly)
And if is is facing in the proper direction.
Second I discovered that my metering rod is a 'lean' rod #75-100.
Wondering if someone has a rod #75-119 they would be willing to sell?
Maybe Walt has an extra???
Thanks for any help!

That is a valve that sucks open when choke is closed tight. It's in correctly and don't fool with it, for if you do, your engine will flood every time you try to start it cold. Walt.

There is a number stamped on the bottom of the base flange where it bolts to the manifold, give me that number and that will tell me carb number and the engine it is for. This to make sure you are looking for the correct meter rod. Walt.

Try The Carburator Shop. He is on the internet. I called the guy for parts when I rebuilt my 37 WDO. He purchased all the stock when carter went out of business as well as the prototype lathe for making the rods. Just give him the carter number and for a price he will send you the correct one. I also used him when I rebuilt the WA-1 on my Twin H, that way I know I have two matching carbs with the correct parts. Having two matching carbs sure helps the car to run right!

Well, I hate to disagree with Walt, but I believe these valves are to allow the pressure to escape in the event of a backfire with the choke partly or fully closed, and thus should be installed the other way around. Without this "pressure relief valve" a backfire would really blow a lot of pressure into the carburetor, and I expect it would spray a good bit of fuel around. To test the theory, I just had Dave K on the phone and he checked three different W-1s he has there, and they were all oriented so they would let backfire pressure escape.
