    Sounds like you have a problem. Was it new out of the box or has it been sitting with fuel in it waiting for it to be sold. It would take it back.

    Who makes the tamp? What Honda engine series? GX200, or GS etc. Is this a brand new, out of the box unit, or "new used."

    This type of erratic behavior (hunting and surging) is caused by one of two problems, Fuel delivery, or the governor. This reads as if your engine is running lean or possibly to fast, that is, TNLS could be a little to much for the carb to keep up with. Carburetors placed on units today are under strict emission standards, and it's not to unusual for this to happen until the unit breaks in, but this also depend on several other factors.

    I'm assuming you mean a "clone" Honda engine? Regardless, if it has been sitting up for a couple of months, start by dumping the fuel (if you have'nt already) in the tank and the carburetor bowl as well. Replace with FRESH fuel (something very recent. like this week, not from the large gas can that's been in the corner for 6-months) and try to run it again.:walking: I'm sure there has been a thread about fuel on this forum, but I'm not looking. "Designer fuel" that's at the pump today is crap, unless you stabilizer it, fuel at the pump has a shelf life of approximately 30 days, give or take. One more thing that you can check is the throttle return spring. That is the small gage wire spring, wrapped around the throttle linkage. If it's damaged and or missing, you may also experience the hunting problem.:waving:

    When you go to drain the float bowl remove the center screw and drop the bowl off, Spray some carb & choke cleaner through the center of the carb where this screw came out then re-assemble.

    Could have picked up a piece of thrash in the main jet causing a leaner run/hunt.
