I found the bolt on the bottom of the blower fan was loose and when I pulled the cord the piston was not going up and down. After I tightened the bolt it was looking like it might start but it would only fire when the primer button was used, there was no gas coming from the carb into the motor on it own. I saw nothing wrong with the carb but I did not check the head yet. I am looking for a manual but nothing so far, I need a breakdown of the carb and what the setting of the idle screw should be.

I had a similar problem and found that the cylinder head had loosened up due to vibration. I tightened the cylinder head and it worked find.

pull the plug, plug into wire, touch head of plug to metal on engine. hold by rubber boot while touching pull starter, see if you get a spark across the plug gap, its small but you can see it. if no spark check switch. if plenty of spark clean fuel system and check primer

Leaf blower craftsman manual


Is it getting gas? Have you tried a spray of Starter Fluid in the Carburetor? to see if it will start on that?
10% Ethanol Gas is a carburetor killer. If the engine hasn't been run in few months, chances are the Ethanol caused problems in the Carb.
Write your congressman and tell then to stop the Bill that has us using this do-nothing Ethanol gas .

I have a Craftsman 794774 leaf blower/vac w/25cc engine that won't start.


Many of these small blowers have an alloy key moulded into the flywheel, if this has sheared it will knock the ignition timing out, and will never run.

Won't start --has gas--has spark craftsman leaf bower


most likely the air filter is clogged, take it out blow it out or spray water through it and allow it to dry completely.

alterinavely, just pouring a small amount of gas onto the filter should make it work, i would do that even if you do clean it properly.

this method works for cars too!

Could be a blocked vent on your fuel tank - is there a vacuum in the fuel tank immediately after it stalls?

My craftsman leaf blower will not start, its firing, getting fuel. will not start even if you put gas in the sparkplug hole


It sounds like the engine is worn out. Have you done a compression test on the engine? If it is not at least 100 psi, the engine will not try to run.
I would get a compression test done on the engine, then take out a loan and go get you a commercial grade blower.
Good day.
