i have an o3 660 and am having some issues with the plug right now, it is getting very black very fast. It also is hard to start and wont stay running all the time. i recently seemed to solve the problem by draining a small amount of gas out of the carb but now it is back, please help any one.

Thanks

 

Hi billy, give us a little more info. Have you had the Grizz for a while and this problem just started, or did you just get the machine? It obviously sounds like it is running way rich so some quick checks like a clean air filter, anybody messed with the carb, or have you just moved from the Gulf Coast to Colorado? Is your plug new and possibly the wrong heat range?

 

hey highcountry the machine is mine from new and this is a relatively new problem, it has a k7n air filter that is clean and the plug is the same kind ive been using all along. no moves or anything it gets around ontario but not too far from home. could it be just bad gas, too high of octane? just looking for ideas to check off over the winter.

Thanks
