Question about Homelite Consumer Products Backpack Blower/Vac, Carb

3 Answers

Homelite 2 cycle backpack leafblower won't run.

The only way to start unit is to spray starting fluid into carb., then full choke. Unit will start but will only run at idle and only if I keep spraying starter fluid. Had this problem prior to rebuilding the carb. No change after the carb rebuild. Another clue; the carb primer bulb only gets approximately 1/3 full after being pumped. Engine has good compression and a new plug. Other engines run on this gas mixture. Your suggestions would be much appreciated.
Thanks, Joe...

    Same exact problem.

    almost feels like it is starving for gas.

    If I move the gas line around, it has a impact on the response.

    I am wondering if the gas line is impinged

    All filters clean

Two cycle engines have a habit of vibrating enough to cause bolts to come loose. You could have a leaky head gasket or crank cover gasket and still be getting excellent compression at the spark plug. If there are leaks then the piston won't be able to create enough suction on the up stroke to pull the gas/oil mixture from the carb at low rpms.

Sounds like the exhaust port is clogged with carbon/oil buildup. My three yr old Craftsman Blower/Vac did the same thing and all I could think of was the carburetor or fuel lines were clogged. But after replacing the fuel lines and air blowing out the carburetor it wouldn't start and then when it did start it only idled. A friend suggested I take off the muffler and cylinder head. Clean out all the old carbon and oil buildup from the exhaust port. It was so clogged up that maybe a bb could have only passed thru. Once I removed all the carbon, put it back together, it fired right up, idled like it was brand new and went to full speed with no problems

Homelite mighty lite 26bv gas Blower won't run full speed or only in Full Choke


Sounds like a lean condition. Rebuild carb, replace fuel lines and fuel filter and you should be ready to blow the leaves.

2-cycle blower starts up but wont run full power rpm


Have you tried choking it about half way and see if that helps? Does it do the same after it is warmed up?

Starts and idles will not run above idle unless choked. Have cleaned carb multiple times new fuel filter new air cleaner and cleaned exhaust screen new plug. Maybe a collapsing fuel line?


Hi,
Have you tried adjusting the carb? There should be two screws on the carb (hi & Low) turn the hi screw completely until it stops and then start the unit. Let it warm up and then begin to back the screw out until it starts to run smoothly but strong. Once you have it running then put it in full run position (choke) and you should be good.
Good luck!

How do I adjust needle valves on a 25cc Homelite UT08111A Backpack leaf blower?


Set the lowend & highend needles to about 1 3/4 to 2 turns each. Choke the carb or prime it, until the carb is wet. Fire up the engine and let it warm up. Let's set the topend first since it's the easier of the two. Go to full throttle. Adjust the topend needle for peak RPM. Leave it wide open for about a minute to see if it changes any. Should the engine go lean, open the lowend needle slightly, if this dosen't work... you will have to adjust the needle valve inside the carb.( I will explain this later) If the topend runs OK, then slowly pull the throttle down until the engine begins to "four cycle" hold the throttle there. Adjust the lowend needle until the "four cycling" barely stops. Now lower the throttle more until it "four cycles" again, and adjust the lowend again. Keep doing this until you reach full idle. Now, from full idle begin to throttle up until the engine starts to bog or hesitate. Open up the lowend needle just enough to eliminate the bog or hesitation.

Hard to start.runs well once started


Some engines are just hard to start, go to any auto parts store and buy a can of "Starting Fluid" spray a short burst near the air intake or near the carbuerator and it should start first pull.

Craftsman gas leafblower


Hey Karl,

To me this sounds like its getting too much fuel after it has been warmed up so either there is too much gas flow to the unit or there is not enough. check your primer bulb once this happens if there is a full bulb when it shuts down chances are its getting too much gas, if its empty then its not getting enough and your fuel filter could be starting to plug up or is not in the tank properly.
