Need some advice - Strange throttle response.

    My Honda GX-31 starts easily and runs fine.

    After a few miles, it won't take the throttle.

    As it accelerates, it bogs, BUT if I let off, it will accelerate again, then bog, let off, same thing.

    Instead of going 22 mph I could struggle along and get back home at about 12-15 mph.

    Has anyone experienced this?

    put the choke half way on and if the problem is worse then your main jet is too rich. If it is better then the jet is too lean.

    consider also that a neglected air filter will slowly clog, causing the mixture to become richer as the air flow is restricted.

    I will do your choke test when it next happens.

    It did not repeat today.

    Nothing harder to diagnose than an intermittent problem.
