Snapper S31SST won't run

Hi,

I've got a snapper S31SST weedeater that's having problems.

From a cold or hot state it will start after about 30 pulls and playing with the choke but it will not continue running well.

I have tried cleaning the spark plug and the air filter.

After cleaning the spark plug I even tried spraying a short stream of starter fluid into the cylinder and then cranking but it just won't pop 'till after about 30 pulls.


As far as adjusting the carburetor of course the manual has nothing usefull. However other then the idle adjustment I can only find one other screw, and it seems to have only 1/4 turn of free play.


Does anyone know what could be wrong?



Thank you,
John

Hello John!

Sounds to me like you need to remove, disassemble, and thoroughly clean the carburetor and install a rebuild kit. First, check your fuel lines and primer bulb for cracks or pinholes, and check the fuel filter in the tank. It could be restricted. Also make sure the muffler/spark arrestor screen isn't clogged.

Thanks for the help.

I cleaned out the muffler and what I could see of the carb. I didn't open the carburator because looking into it it's not gunked-up at all.

Now it's a little easier to start, but at high speed it won't run smoothly.

Does anyone know the possable function of the carb adjustment screw. There is only one other than the idle.


Thanks,
John

It's an air-fuel mixture screw. Try backing it out 1/4 turn or so and see how it does. If the carb is gunked up, you won't see it unless you get it open. I doubt yours is gunked, just restricted a bit.
