I have a cb500 parts bike and just got to the carbs... The outside carb bodies themselves are purty gunky and I wasnt sure if the internals would be junk or not... I saw some hope when I pulled the carbs and saw a clean needle and piston.
I pulled the bowls and it was a beautiful sight. These bowls and jets and emulsion tubes were fantastic. I couldnt believe how the emulsion tubes looked, they were perfect, original jets etc too.... Im trying to figure out what they were all coated with, It smelled a little sweet, and had a tannish tarnish to the fuel bowls that went away with a little squirt of carb cleaner. In one bowl at the bottom it was more of a blackish tan... Ive never had the pleasure of cracking open an old carb that was so well preserved. By any chance does anyone know off the top of their head what they could have been preserved with?
Im also going to switch to non-ethanaol gas as I had just cleaned up another rebuilt pair of cb500 carbs that were gunked up from the ethanaol and the bike not being run dry... Although I heard the marine grade stabil fuel treatment works good.
