Just pulled the machine out of the garage for the season and ran it around the yard. The first time I goosed it, the throttle stuck open momentarily. Luckily, the cutout switch was working the way it is supposed to.

I'm not entirely surprised, it started doing this to me a the end of last season. I've looked and looked and tried a few different things from the outside of the carb. I can't figure out where it's sticking. It only seems to stick when the engine is running, which makes it very difficult to trouble shoot.

Any suggestions as to how to free it up without pulling the carbs out? Can I remove the top covers and hit them with some carb cleaner?

Thanks in advance.
