throttle shaft?

[Rob Daino]

is the throttle shaft replaceable on an original solex single barrel downdraft carb? as mine is worn out!

thx!

Is the shaft worn, or the bushings? 

Bushings might be easier to find/replace on the single barrel carb.

Yes, anything's replaceable.

 

But as John notes, it's usually the throttle housing-

and that can be re- bushed by anyone who works on old carbs.

Autosport Seattle did mine 20 years ago- they do SU's, mainly,

but after a quick glance at the single Solex, said, 'oh, sure, no problems'

back when Seattle only sorta sucked.

Lots of cool carb stuff here including universal repair bushings

appreciate the feedback its the actual shaft that is worn 

[TobyB]

Can be done.  You need someone who can fabricate a shaft.

heh

 

The pump crank off the end makes it a bit more tricky,

but that's just some file work.  I forget- is the throttle plate mounting surface

slotted or just cut away?  I traded away my last singles a few years

back for some Weber parts for the tractor!

 

Most of us, in your boat, fit a 32-36 for tunability and parts availability,

but there's not a LOT of powah to be had there.
