Re: homelite 26bp backpack won't run up to full throttle
I have let my leaf blower run and warm up before throttling up and still it bogs down and shuts down. There is no air cleaner to clean should I just blow out the carb. and fuel lines? It runs and idles just no high speed to blow.

Hi ryan... You still have problems in the carb highspeed circuit..some debris in the passages... BE SURE TO USE COMPRESSED AIR TO BLOW OUT THE CARB. (be sure to watch the inlet valve seat, you can loose it and not even know it) Blow the carb clean in a box or something that will contain any part that may be expelled during cleaning. Please take time to rate me Bud
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.
But sounds like the carbourator is dirty, Probably fouled with old gas varnish. When it is idling give it a little throttle, flip the choke on and then full throttle. If it goes full throttle and doesn't conk out, it is a fuel issue.
On the bottom of the carb. there is a plate held on by one screw, take that plate off and very lightly clean the screen on the carb with a bread tie wire, this worked very well for me. Mine runs great now:)
