Craftman gas leaf blower stopped working suddenly. I changed the spark plugs but it still won't start

Not to sure without seeing or hearing it being pulled over. Compression? Very likely needs some carb work/kit.

Then you will need to check the switch or stop mechanism. If no problem there, then you will need to replace the ignition module.

Check for spark in the new spark plug, if you have spark clean the carb fully and try again. make sure you have correct mix of gas to oil and it is not old use fresh gas oil mixture. Good luck pal.

It sounds like it is time for a new ignition module. Get the model, type and code off the blower housing and go to www.precisionope.com. There you can look up the ignition module under OEM parts.

Were you running a fuel mixture of 40:1(3.2 oz of 2 cycle oil to 1 gal of gas), that you mixed up before you started using it again. The unit may have had to much use on Saturday and may be burned up. Try to have a compression test done on the engine, needs to be at least 100 psi to run. If that proves to be good then you can start looking at Fresh gas mixture, a new spark plug, Carburetor rebuild or an ignition module.

Good Day.

SOUNDS LIKE YOU SHULD GET YOU A NEW ONE ITS CHEPER TO GET A NEW ONE

Diaphram gasket in carb is swelled and air is getting through,get a carb reduild kit and it should be fine.

How long has it been sitting with gas in it ,did you have gas stableizer in it ,if not disassemble carb and reinstall it will start right up...lou

Hi gr2954;

Lots of the starting problems with 2 cycle engines (weed eaters, blowers, chain saws, etc) are caused by leaving them stored for long periods of time with the oil/gas mixture left in them. what happens is that a residue forms on parts in the carb.

Try the following: empty the fresh gas out of the blower. add a gas stabilizer to the existing gas you plan to put in the blower. You can get this stabilizer at any auto parts store. While you are there get a can of spray start fluid. Put the fresh, modified gas in the blower. Take the spark out and spray some starter fluid in the plug hole.Replace the spark plug and try to start the engine.It will probably take a few cycles of doing this to get the blower to stay running.
when you put the blower up for a long period, empty the remaining gas out then start the engine and run it till it stops. this gets the remaining gas out of the carb.

Similar experience with the same blower. I cleaned the carb checked for spark but I still can't get it to start
