I have a G400 on a genset that has been sitting under the bench here for probably 15 years since it was last run and as you would expect the carby was gummed up. Problem is I can't remove the main jet and the screw slot is starting to damage and I doubt I will be able to get it out. I was wondering if putting it in an ultrasonic bath would be enough to clean the jet holes or am I expecting too much of it. Any thoughts
