You were the guy I was thinking of when I posted the heading Dave!
Now see Doug, that’s what I’m looking for. I don’t have any idea what a YF3211 looks like or what the mounting hole centers are or which side the linkage is on or where the inlet is.
Jon, I know it's a business with ya but I like to feed my brain and tinker with my own stuff. Keeps the Alzheimer’s in remission. I hope ya can understand why I didn't take ya up on all those "B" cores, I haven't found a good one yet and I didn’t want to get stuck with a bunch more unless I can figure out a way to keep them from leaking. Since you say that you won’t service them either I’m assuming that you haven’t figured out a way either. The heat treating does relax the casting and flatten it out somewhat, however It also distorts some of the other features. Such as the venturi is very slightly out of round and the choke butterfly is a little stiff. The power piston well is distorted also after heat treating, just enough that you have to hone it a few tenths to get the piston to slide freely against the compression spring.
I’ve made up cad drawings of some of the brass parts in the “B” carbs. They can all be made up on a small engine lathe. So far I’ve made up power pistons, idle adjustment needles, I’ve got the drawings made up for the jets but haven’t made any yet. I picked up a box of SS dowels for the floats and now have boxes of all the Fillister head screws that are always rounded out from using the wrong screw drivers. I’ve made up a double ended form that fits inside the two float halves after you unsolder them. With this I can straighten out any dents that may be in the floats, also I can spin soft brass disks over them to make new float halves if I need to.
Now all I have to do is find the secret to keeping the two halves sealed.
Are there any problems with the W-1 carbs? If it was a good carb then why did GM switch to the Rochester “B” in ’50 and use it on all the inliners for a decade?
So it looks like I’m stuck without carburetion for July also. Are all these AD’s I see in the pictures with their hoods popped up and a cute little Rochester “B” sitting proudly on the intake manifold just trailer queens?
