It sounds like the Low side circuit of your carburetor needs a small adjustment. If you can, turn the L screw (the screw in the carb body closest to the engine) out 1/8 to 1/4 of a turn. I will include a carburetor tune tutorial so you can understand more. This usually cures the acceleration issue IF the carburetor is not in need of new diaphragms.

I use an automotive type wire connector tapped onto the head of the L or H screw in the carb to grip it to facilitate adjustment. The plastic ends on the wire connector can be forced over the screw head and grip it. A ring-type terminal connector works well as you can grasp the ring and turn the screw once the plastic crimping end is on the screw head.

The high-speed carb jet may be fouled. Most 2-cycle carburetors have two adjustable jets, one for idle, another for higher speeds and loads.

Starting procedure

Terry: According to eHow.com:

"
  • Put on a pair of safety glasses. Remove the fuel cap from the Weed Eater and set it aside. Fill the fuel tank with unleaded gasoline that has been mixed with quality 2-stroke oil in a 40:1 ratio. Replace the fuel cap.
  • Move the Weed Eater to a safe place and lay it flat on the ground. Depress the fuel bulb located beneath the carburetor approximately six times to prime the engine. Press it slowly so that fuel has adequate time to traverse the fuel line.
  • Slide the handlebar-mounted engine "On/Stop" switch to the "On" position. Slide the choke lever beneath the fuel tank to the "Full" position.
  • Depress the "Throttle Lock" lever located beside the engine "On/Stop" switch. Keeping the lever depressed, squeeze the throttle trigger. Release the throttle lock. This sequence holds the trigger in the depressed position, which aids in starting the Weed Eater.
  • Roll the Weed Eater so that it is resting on the engine and the trimmer head shield only. This will allow the spinning trimmer head to avoid contact with the ground. Brace the Weed Eater by holding it to the ground with one hand. Using your other hand, pull the starter rope quickly until the engine begins to run. Do not pull the rope more than a dozen times. If it fails to start by then, squeeze the throttle trigger and continue to pull until the engine starts.
  • Allow the Weed Eater to warm up for about 15 seconds, then slide the choke lever to the "Off" position. Let the trimmer run for another minute without touching the throttle lever. After the Weed Eater has warmed up, squeeze the throttle trigger once to disengage the throttle lock. The trimmer is now operational.

    Tiller runs at full throddle and tines continue to turn. Unable to lower throddle. What do I do?

    Sounds like the throttle cable is sticking or the carburetor butterfly is sticking.
    Squirt some WD-40 into the cable that attaches to the throttle handle and onto the mechanism the cable hooks to at the carburetor. Carefully actuate the throttle and see if the mechanism is moving smoothly. It may need several squirts and some actuation before it become free.

    The tines on a honda f220 always spin and don't change speed when clutch is engaged but speed up when throttle is increased. Adjusted cable with no luck.

    I believe that unit utilizes a centrifical clutch. try decreasing the idle speed and see if the tines stop. They should then engage as throttle is increased.

    Hello: Remove the ducting going from the air cleaner to the throttle plate, clean the carbon off the throttle plate and the throttle body bore. Do not spray excess carb cleaner into the throttle body. Hold the throttle plate open with your hand and spray carb cleaner on a soft rag and clean off carbon. When finished key on engine off for 10 seconds key off for 10 seconds do this a total of three tines.

    If the motor will accelerate, does it sound like there is a load on the motor? If the motor accelerates easy and does not seem to be under a load you may have a problem with the clutch. Are you getting power thru the clutch to the gearbox?

    Just bought an older Mantis 2 cycle tiller. The tines engage when the tiller is started. Of course that makes it hard to start with the tines on the ground! I don't believe it was doing this when I...

    if the idle is too high the tines wont stop due to the tiller tines are run by a "centrifuigual clutch" which means when you increase the throttle speed the tines will start to turn : there are 2 adjustments you can try,1) adjust the idle screw under the carburetor where the throttle adjustment and a triangle piece of metal touch(your throttle cable wire will be attached to this triangle) ,if the triangle and idle adjustment don't touch and there's a gap between these 2 pieces close the gap by adjusting the 10mm adjusting nut,this will correctly set the idle #2) adjust the idle adjustment screw talked about above till the tines dont turn with throttle set at idle or lowest speed setting
