I’ve looked at some suggestions for cleaning up carbs in an ultrasonic machine but wondered what would get rid of this?
I’ve used water and washing up liquid and had a scrape but it’s getting into the nooks and, of course, crannies.
There are quite a few specialist companies that strip, clean, inspect and refurbish carbs, often easier than messing with it yourself, they have all the kit and the experience, and parts, I sent the carbs from my old BMW away as it never ran right from the day I bought it! previous owners abilities were not in line with his confidence, there was some internal damage and a hairline crack from heavy handed use
came back spotless with new parts, and the bike ran smoother after that
