    If you’re changing or cleaning a plug every day, and this happens when hot, but runs fine when cold, it sounds like a severly plugged air filter or a stuck choke. Possibly a lot of build up in the carb, but if it idles fine cold, probably not.

    Someone else mentioned magneto/ignition problems, this is possible as well. But start with the basics first – good maintaince – clean the filter and carb, check the choke (if it has one, I’m not really sure with that model), make sure you’re using the right plug.

    Its possible, but its also possible that you have some build up in the carb. bowl that’s clogging the fuel jet. If you had it sitting for a long while that’s the most likely issue.
