    Not sure if there should be a spring or something on white lever. String plays out continually, and cuts off in 2 or 3 inch pieces.

Starting procedure

Terry: According to

  • 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.

    I replace cab kit on a zama 2 stroke cab and i found a bearing and small spring and do not where it fits

    If you took the rod holding the choke out, then its the detent that hold choke in the different position's. Remove the rod and under it on the top end you'll find a hole in carb. housing, put the spring in first the ball and slide the rod back into place.

    Need to know how the spring goes.

    It is really hard too tell in writing how the spring goes back.
    It's look like the spring is pushing be the lever, so please try to figure it out in which position is pushing it back, the spring can be installed only one way, to work properly.
    I hope you will figure it out.
    Good Luck

    Where does the little spring go inside the carburator?

    Hi loneoaktrail...

    The little spring inside of the carburetor goes under the float arm.
    That is where your fuel inlet needle/float valve is located...on the arm at the end.
    Normally there is a small indetion in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.
    The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.
    Your carburetor should be working properly to run now as long as you do not have other problems in the fuel system or electrical problems.

    I was given a used 31cc trimmer but can't get the spool off to replace it. how do i do this?

    A typical trimmer has a small bump knob, an inner spool with the plastic string wound on it and the housing for that which is the string head.To remove the small bump knob, hold string head firmly and turn the bump knob counterclockwise. To remove the head entirely, first remove the bump knob. Next, remove the inner spool with string. What should be left is the spring with the end of the gear shaft showing. Some heads are locked on and some just slip over the end of the shaft. Check the gear drive just above the string head for any holes in the collar. An object can be placed in one of the holes to lock the drive and twist the head off.Ryobi's use retaining clips on the shaft which have to be removed.

    On pulling the starter cord, there is a rattling noise as if a nut has come loose. The motor does not kick over.

    When you pull the starter cord, three things are happening inside;
    The cord is spinning the spool that it is wound on, the spool has a gear or molded teeth which engage the motor through spring-loaded levers, and a coil spring returns the spool to it's original position...hence the name "recoil" starter.

    The first possibility is that the gear has come loose (if a mounted gear) or broken (if molded to the spool), and the rattling is the loose part(s) flopping around instead of engaging the motor.

    The second possibility is that the lever springs are a bit dirty/rusty or bent and stuck out of position, and the gear/teeth of the spool are just banging across them instead of engaging.

    Start by removing the plastic cover(s) to gain access to the starter rope's origins, ie; the spool and the starter levers.
    The recoil spool with sping are likely attatched to the cover as a unit, so you don't have to go any deeper into the recoil.

    Check the drive gear/teeth for a solid mount and teeth damage (they are saw-tooth shaped), then check the 2 small levers mounted to the crank for free swing and solid springs...a drop of oil or WD40 at their mounts won't hurt, just wipe the excess and while you're there, clean the magneto face and the magnets on the crank with a little WD40 on a rag.
    * Don't despair if they look's entirely possible that they were stuck out of position until you pulled the recoil, and a decent cleaning will keep it from happening again.
