SOURCE: My weedeater won't run in 'run'.

Sounds like the carburetor needs adjusting. The owners manual should show you how to adjust the carburetor. If not, I would take this to the place of purchase and ask them to repair or replace it.
It should be under warranty for at least 2 years. I have had the same problem and when the carb would not adjust to run properly. I took it back and got a new one . This was at lowes and they were really great about it. If you decide to return it, clean it up real good.
In california we have different regs on outdoor power equipment and can adjust the idle only. The carbs are different for the rest of the US.
They can usually be adjusted, If not take it back. You deserve to get what you pay for without problems like this.

SOURCE: Craftsman 32cc Trimmer Runs with choke at idle, then stalls

Sounds like somewhere you have a air leak. Most likely it's somewhere near the carburetor intake or maybe the carb itself. Could be a line from the primer if it has one and i do believe it should that could be leaking or loose. Good luck.

SOURCE: weedeater will not run with choke off

Check your carburettor mounting screws,they might be loose and it would mean the engine is
getting to much air and it would leak gas. Stephen

SOURCE: I have a Craftsman 32cc weed trimmer, can't give gas, it stalls

Usually the diaphram is wore out. It is a relatively inexpensive part. Does it run better with a little choke? If the answer is yes chances are it's the diaphram. Also sometimes the adjustment screws can move. There are two, one for low speed, and one for high. With the engine warmed up make small movements on the screws (some are marked low, and high) in, and out adjust til the engine runs at its optimum.
Hope this helps!

I have a craftsman 32cc weedeater and i have replaced all the lines and filters cleaned carb. it will start but after about a min r if u pull throttle it dies what will cause this problem


The motor dies because it is "going Lean" at that point and not receiving the influx of fuel it needs to throttle up. A couple of elementary things cause this. 1. The fuel pump diaphragm inside the carburetor is not functioning properly due to losing its flexibility. 2. The carburetor L mixture screw needs adjusting.When you open that throttle you are telling the carb, OK. playtimes over, let's go. The carb is supposed to respond with fuel from the L (idle) circuit and the H (high speed circuit) mixture areas. It dies "lean" because the fuel from the carb isn't getting to the main jet or it is insufficient quantity, because the L speed circuit is NOT contributing enough fuel
So adjust the L screw (one closest to the engine) on the carb OUT 1/8 to 1/4 of a turn. Unconventional heads on thes carbs require special tools or a little ingenuity to get ahold of them.
You may need to install a basic gasket and diaphragm kit in the carb to restore the functionality of the fuel pump and the fuel control system. Here is a carb adjustment tutorial.

On small 1985 14 inch craftsman chansaw what is the high and low settings set on the carb


Not knowing the model, you can always look on the body of the carburetor, there should be an "H" for the high speed mixture screw and an "L" for the low speed or idle mixture screw. Both screws should be set initially 1 to 1 1/2 turns out from seat and then the carb. will have to be fine tuned from there. The high speed screw is adjusted when the throttle is in fast position, at 1 1/2 turns out you should have a slightly rich mixture so you may need to slowly turn it in until you hear the saw's rpms start to increase. You want to find a medium point between too rich and too lean. The low speed or idle mixture screw is set the same way just at idle rpm instead of full throttle, find a medium between too rich and too lean. You should be able to throttle form idle to wide open without any "lag" or "stumbling". You can also offset any rpm change at idle with the idle speed screw (not to be confused with the idle mixture screw). Hope this helps.

I have a 32cc craftsman weedeater. I put new fuel lines on it because they were falling apart, and I don't have the fuel filter on it right now, will that make a difference? It will start, but as soon as I...


Hi, yes the filter is in place to protect the delicate workings inside of the carburetor. Something my be blocked partially letting some fuel pass but when the throttle is turned up the supply cannot match the demand and it fails. Try to give the carb a good cleaning. If the the fuel lines are such that they need replacing then the carb itself could probably use some attention. hope this helps.bv
