C20CPR problems

Hello everyone,

My C20CPR has been having some problems. I've been starting it up every once in awhile just for fun the past couple of weeks. The high speed setting didn't work. Then today when I fired it up, the high speed setting worked. (This is a choke model by the way.) Then, I tried mowing with it a little. It would run ok, then out of no where, it would rev up real high and then it would continue to run ok again and then repeat the same process. What's wrong and how can I fix it?

Thanks in advanced!:fing32:

This might be simplistic...but check the plug and gap. If it runs good for awhile sounds like something is moving in the carb or getting sucked intot the carb or fouling. Are you sure your gas tank is CLEAN inside and there's not a clump of schmootz making its way into each carb?
