400F. carb set refurb
« on: December 10, 2025, 06:37:19 PM »
I'm still working my way through my junk box and picked up the frame that the 4 carbs attach to. I have everything else to build another set of carbs.  It's seized solid so kind of expecting to make up some new bronze or brass bushes anyway.

I parked this many years ago due to the metal rod that actuated the slides being quite sad scabby and because I didn't have the  machining capability machine the two keyways to produce a new one.

What do other people do, I can live with a few scabs where they are hidden under the tank but it's the two ends that have the inverted cone that is difficult to clean up not knowing what material it is. 
 

It's not zinc plate but could be nickel or chrome plated that has been ground to size.


Any ideas or suggestions.

Regards Dave

This is a link to Max who used to be a member on here.
He makes the link rod from stainless with the keyways machined into the rod. I've bought one as have a few others and they are absolutely perfect. He makes other parts for the 400's as well.
Contact him through his eBay site and let him know your are a forum member and you may get some discount. I think I paid £40 as my one was one of the prototypes, they may be £50 now but well worth it.
I tried to get my original re hard chrome plated by Phillpotts, they wanted £140!
