Carb cleaning methods

Had a great day today cleaning up my XJ750 carb parts. It was great because I finally found something that works really well - white vinegar and a toothbrush. Good degrease, then a half hour soak followed by a toothbrush scrub and they look like new. For the zinc plated parts I soaked them for another half hour in a fresh solution, rinsed then finished off with some wadding polish.

When I got my XJ750 it had been sitting on the side stand for two years and the carbs were really disgusting, like gummed and corroded up to the max. Now the bits look like new !! Stay tuned for another XJ renovation ...

 

Yesss Even Ketchup immersion works well Due to the Vinegar content.
However it's the teeny internal passages that are critical to clean Not just the outsides. G'luck.

 

Does White Vinegar shine up the brass jets or do they turn black???

 

Yeah, it seems to shine them up by removing all the crud and the oxides. They still need a bit of a rub afterwards though.
