I used to fly RC (about 15 years ago) but marriage, a career & kids pushed my hobby to the back burner.

Now I would like to get back into it with my sons. I have a .40 sized trainer with a OS 40 FP that is pretty gummed up. The shaft turns freely, but the carb is sticky.

what can/ should I do to free up this little engine for use again?.....or is it worth the effort vs. buying a new one for around $60?

thank you for your help.
