Stuck throttle spindle on B Zenith

Hi all,

So I'm slowly starting to evaluate my '32 banger's status and works required, and first problem is the throttle spindle is damn well stuck. It moves fine on the side where the linkage is, but on the outside it just won't budge.

I've tried penetrating fluids, cooling, heating, all to no avail. This is pretty well seized.

Funny as I'd always feared the external ****erfly (for the choke) would be the one that would stick more easily being more exposed, but that one works fine!

Soooo... any further suggestions? This is the banger's original carb. Am I going to have to drill it out? Are there easily available spindles and throttle plates? I see a lot of stuff for the A out there, not sure if it's the same?

Is this just a lot of h***le for a lousy carb that I'll end up removing, or is it easy to solve? I'd like to try and get it running properly with all the original stuff if possible before going into modifications...

Thanks in advance for your thoughts on this.

Cheers, Eddie

 

Tap the shaft endways as much as you can...you can apply more force that way without destroying things. If you can move it at all, keep oiling to try to float away rust knocked loose in there. Alternate your rust therapy with soaking in Evaporust if you can get it... it has a small amount of penetrating ability and can actually dissolve the rust it manages to reach without harming anything else. When you go from oil to evaporust, swizzle the piece in paint thinner first in order to get the oil off and allow the water based material to work.
I think Renner's corner and Sacramento vintage Ford may have the best collections of B carb parts.

 

Bruce hit it on the head for dis***embly. Coincidentally I have one sitting on my lap now I'm rebuilding to sell. The throttle shaft at the carb is not the same as the Model A carb.

 

If you get into trouble...some of us have dead B-based industrial carbs lying around as organ donors. Do check out those catalogs to see if shaft is available, though!

 

Thanks, guys... I'll try the tapping idea, see where it gets me...

Bruce, never heard of Evaporust, will try to find if it's something available on this side of the world or if there is any other equivalent, I'm always willing to try new stuff. I just wanted to make it run good before actually getting into modifications, so I can have the first-hand experience of what a B drives like. Then see what I'd like to improve and go from there.

Cheers, Eddie

 

Evaporust in my experience matches its advertising...it attacks NOTHING but rust. Not even zinc. Its penetrating power in crevices like inside bore for throttle is limited, but there is some. Get all the oil offathere first.
One reason I like it is that I can throw stuff like an entire stromberg (made of world's softest zinc) in there without worrying about soft part damage, and leave it in there for months if I care to because it will not eat away at the iron either.

 

Bruce, a little question: I've found two different products by the same name, which one did you use? Both have dot com webpages, one hyphenated and one not. Both have sales agents in Europe, so I'll be trying to get some.

Cheers, Eddie
