Question about Craftsman 4 Cycle Blower/Vac

2 Answers

Leaf blower will not continue running unless primer bulb is pushed intermittently

This is a 2 cycle blower. I just replaced the primer bulb and fuel lines on a Craftsman leaf blower. It starts fine but seems to run out of fuel. I can keep it running by pumping the primer bulb every 5-6 seconds. I checked the filter and it is not blocked. Lines are not kinked.

    My leaf blower starts fine and for about 10 minutes then it stalls. When I remove the air filter cover, I find the foam air filter soaked with fuel. Do you have any ideas what would cause this?

After replacing primer bulb, engine hesitates and will not run full throttle


Make sure you connected the lines correctly. If this is a primer assy that has the 2 barbs on the back here is a picture of how the lines should be connected to it as well as the carburetor

Now if this is a primer bulb on top of the carburetor then disregard the previous answer because in this case, your carburetor needs the H needle adjusted. Go on you tube .com and type in how to adjust a 2 cycle carburetor. Many videos will appear.

Ryobi instruction manuals


The primer does not necessarily need to work for the unit to run. It does have a choke to aid cold starts. However it is a good indication of something wrong in the fuel system. A primer bulb that does not return to shape or does so slowly indicates a clogged screen in the carb. Check the fuel filter and fuel lines. Replace the fuel lines if they are stiff or discolored, rebuild the carb and replace primer bulb.

How do I replace the fuel bulb?


Homelite and Ryobi appear to be made by the same manufacturer. Home Depot now carries a "Fuel System Tune-Up Kit, AC04122," that includes 2 replacement fuel lines and a replacement Primer Bulb for 25cc, 30cc, and 26cc 2-cycle engines. Cost is $7 +.

Fuel leaks bulb not priming.


If you have a leak the bulb will not prime. Over time the either the rubber on the primer bulb gets a pin hole in it requiring bulb replacement or one of the fuel lines cracks and introduces air into the lines. Unless the system is completely sealed the primer bulb will not work. Make sure all of the connections on the fuel lines are tight and correct the system leaks.

Thanks for choosing FixYa.

2 cycle leaf blower will not start. If you pour furl inti the carb it will start until fuel is gone. I have rebuilt the carb with new gaskets and seals.


Does it have a clear primer bulb, and are you using it when starting a cold motor? The primer bulb should be filling up with fuel after you push it in several times. If you are not getting fuel in the primer bulb then there is no fuel supply. One common cause of that, in old leaf blowers, is a broken flexible fuel line going to a weighted fuel filter in the tank. The flexible line allows the fuel pickup (the weighted filter) to remain at the lowest part of the tank when you hold the leaf blower at different angles. Another cause could be a bad adjustment of the float valve, or clogged fuel passages. Did you blow out all the fuel passages when you rebuilt the carb?
