I've noticed that mine has acquired the habit of idling around 3k when it is warmed up with the choke in. I assume it is an air leak and tried spraying some carb cleaner around the carb boot but there was no noticeable change in rpm or anything. I pulled the air filter and the foam element has a large hole in the center and the rest was crumbling away. Could this be the cause or should I look for something else?
If it ain't broke, give me a minute.
