Weedwacker stops when you squeeze throttle trigger - why?
Anopearl28
I am not a pro at this topic, but have been successful at maintaining my weed-eaters for years. That being said, the machine needs three thing to run: Fuel/air mixture, compression, and ignition. You obviously have compression and ignition or it wouldn't start up at all. So leaves us with fuel. Either too muc or too little fuel. If you have a strong odor of fuel after it stalls, then it is probabl too much. However, it is my experience that you are getting too little fuel. Firstly, it could be as simple as a fuel filter. If it stops almost instantly, it probably isn't. Most weed-eater carburetors have 2 fuel "circuits": Idle and high speed. The idle is probably working fine since you said it idles. When you press on the trigger, the carb transitions from the idle circuit to the high-speed circuit. If no fuel is coming out the high-speed ports, then the engine is starved on fuel and shuts down almost instantly. This can be caused by a couple of things: 1) If you left 2-cycle fuel in the tank last fall and didn't run all the fuel out of the carb, then the 2-cycle oil gets gummy and clogs up holes(or fuel ports) better than spackle. For this, take it to a professional and have them "boil" the carburetor to get the crud out. This really needs done by a good shop. call around to all your friends and get references....a good carburetor-rebuilding capable shop is hard to find....oh yes, any of them can get it running again, but it is like a car that has been wrecked...it will never drive the same again unless the repair tech knows there stuff.

First remove the barrel action by unscrewing the only bolt that attaches it to stock. Then loosen the1/2 nut that hold the magazine in place, this will allow the magazine to rrelease fom the bolt.Lastly, pull the bolt backwards and when it stops, squeeze the trigger so it will depress the sear.the bolt is now out.

Check the vacuum hoses for leaks or cracks to start. Make sure that the throttle return is allowing the throttle cable to return back to the "rest" position.
What do i fix when the lawn mower engine stops 2-3 seconds after it starts unless you continue to prime it?
One thing I have done is check the spring on the throttle. I had this happen and the spring that holds the throttle in a specific location had come unhooked. I simply held the throttle open, had another person sstart the mower and then reattached the spring to hold the throttle open in the desired position.

You're probably holding the throttle too tightly. Vibration from the bike or the cold can also cause the numbness, try riding with gloves on. If you're on a long ride, take frequent stops.
