SOURCE: Leaf blower will not achieve full RPM's

try removing the muffler and scraping out any carbon build up in the exhaust mouth of the block. if that doesnt help you will probably need to replace the carb.

SOURCE: BX 90 homelite leaf blower two idle screws

The initial setting is 1 1/2 turns out. Screw them all the way in and them turn them 1 1/2 turns out. This is the starting position and should start, it may need some final adjustments to run like you need it to run.
Remember more the screw is out the more fuel it will get.
Good Day.

SOURCE: My Ryobi RBL30MVA. leaf blower will not start,

I have had this exact same problem with the same model after just one hours use.

Returned it a week later and after 2 months the replacement did the same thing.

Returned that one and got a third. A week later that ones doing the same thing again after only an hour or so use.

Obviously some defect in them.

I'll be getting my money back and visiting the local mower center to get their help rather than doing the guess work my self and ending up with a dodgy model

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.

Blower does not stay running


Make sure you have the propper mix of gasoline and oil. If the fuel is old mix new fuel to proper ratio. Find your manual and find the low speed fuel adjustment and the high speed fuel adjustment on the engine. First, turn the screws in and count the turns so you know where you started. Return the screws to the origional position. Usually 2 to 2-1/2 turns are a good starting point if you get them messed up. If the engine runs with the choke on you have to open the high speed jet a bit, 1/4 turn CCW. Keep trying this and get the feel of the change in the engine performance. If you have too much fuel the engine will not get to peak RPM. The low speed jet works similar but you have to adjust it so the engine idles at a decent RPM. This should get you on the path.
