Post by: bbrian66 on November 03, 2026, 05:18:16 PM

Is there likely to be any chance of rescuing these carbs...?

I would see how the structure looks when you remove the crud with something soft like a tooth brush/paint brush and WD40 spray.
On my 400 the sliders were stuck solid after 10 years of standing.
With patience I managed to release all four sliders undamaged using fresh petrol as a solvent, soaked overnight in a sealed tupperware type container. Three yielded in 24 hours, one took several days, refreshing the petrol every day.

Certainly worthy of a clean!😁

I’d be surprised if the body wasn’t severely weakened by that amount of corrosion

It's tempting to give them a clean and see what's left

Nothing ventured nothing gained. Worth a try, you never know.
