Do you have an ultra sonic cleaner? If so, drop the carb in it and let it cycle a few times and give the screws a try. They probably are corroded and giving you the grief of not wanting to come out. The overnight soak should yield some good results, though. Just be mindful of what you soak it in; you could damage rubber/plastic parts if you leave it in the wrong solution. Also, if you have an impact driver, use that to free the screws.



Do you have Larry's Carb Book? If not, then it would be a good idea to get a copy. It will pay for itself!
