SOURCE: Cuts out after 10 minutes

Sounds like fuel tank vent problem , air has to get into tank
sometimes its vented by fuel cap but a lot of hedge trimmers use
a duck bill valve right thru tank or hooked to hose .
To test if this might be the problem loosen gas cap when it starts to die .
good luck

Had same problem with my reconditioned unit. After a few hours engine would run only with 1/2 choke and full throttle. Like most 2 cycle engines, the unit was starving for gas.

Solution: Adjust both carburetor screws. These screws are located directly below the idle adjustment screw. There are 2 of them side-by-side and they are approx. 3/16 diameter with an oval shaped cast metal raised restricter. Simply remove the plastic round air filter by removing the small nut. Then, using a Dremel tool while wearing safety glasses, cut a slot in the face of each screw. Cutting through the raised cast metal surrounding the screws will not damage the unit. Then using a small flat blade screwdriver, screw each screw clockwise till it stops then back-out each screw 2 turns. Factory setting is 1 - 1/2 turn each. However, the unit over time runs too lean with the factory setting.

Then start unit, let warm up with 1/2 choke, then turn to run position and make any final adjustments.

Making this adjustment, I am once agin able to trim my yard in the idle position. Runs Great !!!! Hope this helps.

SOURCE: Craftsman 25cc weedwacker (358.791030). Zama

need to adjust the high sscrew. i do mine in 1/4 turns. start machine, full throttle, adjust the h(high) til it clears up.i would start by turning 1/4 counterclock wise, just remember to keep track, in case it runs worse, the put it back to orig. then try the other way. but i suggest 1/4 turn at a time

example... think of a clock when turning screw. straight up and down, 12oc, 1/4 turn will be 3oc, another 1/4 will be 6oc, and so on. hope it helps!

A lean mixture can cause hunting. Locate the mixture screw on the carburettor (there are two other scrws here but these act as stops to adjust the high and idle sppeds of the engine) and after the engine warms up, try turning it a quarter of a turn anti-clockwise and see what the effect is.

Won stay running


Needs a carb adjustment, cleaning, or possible rebuilt. Try adding a little seafoam and running at half choke for about 5 mins or longer this may clean it up nicely. also check the spark plug.

The motor does not respond on full trottle, half and up it just like chokes itself


You need to adjust the high speed mixture on the carburetor. When you say it 'chokes itself' you imply it is too rich.

Carb and throttle adj.


Here is how to do it. First disconnect the throttle cable to the carb and let it hang loose. Make sure the outdrive is in neutral and the boat is secured to the dock or on a trailer with a water ****.

Pull back on the throttle by hand directly on the carb throttle shaft. Observe the Choke cam on the opposite side of the Carb. Let go of the Carb throttle shaft and see where the Stepup Cam is set. The Choke plate should be closed most of the way. You will not have very much time to make an adjustment.

Start the engine and let the Choke work and observe the RPM. There are usually adjustments you can make to put the Stepup Cam on a lower step by bending the Link Rod if it is running too high in Choke. Sometimes the Cam is left alone and a screw similar to the Curb Idle screw on the Throttle side just needs reduction to ride lower on the Choke Cam.

After the Choke is warm, it disengages with a pull on the Throttle. Now you are using the Throttle side of the Carb to operate the engine RPM. You want a low RPM for sake of the outdrive gears and NO WAKE zone. The adjustment screw opens the Throttle shaft, You set it for the Manufacturers Spec. probably 550 RPM.

The Throttle cable is now adjusted so it pushes slightly against the Carb. This forces the throttle closed. The Throttle cable has threads and a sort of Knurled knob which runs on these threads. This device is used to lengthen or shorten the cable so that pressure is applied against the Throttle.

When the outdrive is in water you will has resistence on the Exhaust. This will slow the RPM. If the motor stalls you will need to adjust the motor to idle Specs while in the water.

For best economy, find a Vacuum port and attach a Vacuum guage to it and adjust the air mix to the highest Vacuum reading then turn in the Mixture screws slightly until the vacuum starts to drop.

Blower does not stay running


Make sure you have the propper mix of gasoline and oil. If the fuel is old mix new fuel to proper ratio. Find your manual and find the low speed fuel adjustment and the high speed fuel adjustment on the engine. First, turn the screws in and count the turns so you know where you started. Return the screws to the origional position. Usually 2 to 2-1/2 turns are a good starting point if you get them messed up. If the engine runs with the choke on you have to open the high speed jet a bit, 1/4 turn CCW. Keep trying this and get the feel of the change in the engine performance. If you have too much fuel the engine will not get to peak RPM. The low speed jet works similar but you have to adjust it so the engine idles at a decent RPM. This should get you on the path.

1976 Gran Torino motorcraft 2150 2bbl carb. Starts and runs ok at high revs but as choke eases off and revs decrease, engine stalls. Fuel pump OK. Float levels and choke pull off OK. No obvious vacuum...


Are you sure your idle ports ( size of pinhole) in carb aren't plugged with something? What happens if it starts to die, and you give it a quick squirt of WD-40 , down throat of carb?
