Craftsman weed wacker: won't take the gas

I haven't any owners manual....do to aging and keeping the tools all lit up and ready to work..by myself.

Well heres my problem; My weed wacker starts a liitle tougher than it did.But...once its running, If you try to give it gas .....by the trigger, It doesn't want to increase in speed this is after it warms up. If I slide the small "choke lever to start". It will run wide open perfectly.Pull the trigger at this point and it goes down and dies.The tool
isn't 4 years old yet,but i am not sure about that.. I put new "mid grade" gas and 2- cycle oil mixed properly in it.The small plastic hoses.-------- i pulled the filter,,, out, Filter took air when blown air thru it,Have i given enough.info for anyones input on this?
thanks much for stopping by to help bob s

It seems to me that the engine is getting sufficient gas to start but not enough to run. I'm confident it's the fuel filter. If that doesn't work go to the carburetor, but I doubt that will be necessary.

Prolly just needs the carb adjusted, if it has adjustments. Without a model number I have no way of knowing.
If it does, back the H screw out a bit.

Post the model number so we know what it is, sounds like the carb is varnished a little, a good dose of seafoam might clean it up if you could keep it running. Have a good one. Geo

that mechanic in a bottle crap has proved many times to be as useless as teets on a bore hog
Had it all demonstrated to me and while it might work once in a blue moon, it is meant for fuel injection which has pressure on the clog. Carburetors work on vacuum so the source of pressure, or lack of, is on the other side of the clog...
Not to mention, they all advise to add there agent directly to the carb or fuel inlet for at least 15 mins, this does not mean pour it in the tank and voila....you have to rig up a source for their juice to be directly injected into the carb. Again, in fuel injection you have a pump that pushes the juice to the clog...in a carb, the vacuum can not draw the juice through the clog most times.

I have been using SeaFoam for a long time and think it is an excellent product and if it only works in a blue moon, I guess I have experienced many blue moons. Have a good one. Geo

I generally agree that mechanic in a bottle type products don't do anything more than lighten your wallet, but I have to say that seafoam is an exception to that rule. I have seen it work many times first-hand and I now am a believer. It's good stuff.

As for the problem with this trimmer, I'd open the high speed adjustment screw 1/8 turn or so and that should solve your problem. It's the one of two side by side screws that is closest to the air filter side of the carb.

BFH fixit Do you know where i can get the "carb adjusting tool" hex head craftsman No luck with a ball point pen.? bob s model# 358-791060 serial# 0808---7N702-176

When i reinstalled the 2 plastic lines .Did i make a mistake?...the larger of the 2 lines, i put the filter back on.slid it in the tank. The other very small plastic line--slid just slid back in the tank ..far as i could push it, before folding it up or breaking it.Is this right/?? bob s

The fuel filter goes on the small line, the large line is the return and only need to be in the tank 1in or son. Refer to the diaghram below. Have a good one. Geo

As long as the line with the filter is the one that the carb is drawing through, that's the main thing. If you have the filter on the return line, you'll be back to cleaning the carb again in no time.
