Runs slow


In California the new blowers have sealed mixture adjustments and you need the have your carb. mixture adjusted be a qualified shop. If your carb. HAS mixture adj., turn the high speed mixture so it runs best at high speed, then turn another 1/8 turn counter clockwise to be a little rich. Then at idle adj. the other screw till it idles best.

Blower bogs down and kills at full throttle


Check the following, then clean or replace:
  • Fuel Filter - Located IN the fuel tank
  • Spark Plug
  • Spark Arrestor - at muffler port, creates resistance of exhaust flow, engine then bogs
  • Carburetor - may need a rebuild kit
Then watch this...

42cc 18 inch craftsman chainsaw model 358-351910-18. Saw runs great at idle or while not cutting wood, when starting to cut wood just after the entire bar gets into the wood engine bogs down and chain...


Generally this is a fuel / air ratio problem. Usually it can be solved by a carb adjustment. On the carb there are usually two screws, one marked low or L , the other marked high or H. Low is your adjustment for idle mixture, high is for mixture at full throttle. The saw should Always be adjusted to run well during the cut. Make adjustments a little at a time, then try The saw. Continue small adjustments untill the saw is performing well at full throttle while Cutting.

Blower not running at high rpm when full throttle. Cleaned air filter, gas vent, gas filter and spark plug. Blower is 3 years old. Have not bought any new replacement parts.


Try removing the muffler and look inside of the exaust port, you should be able to see the piston in the full opening of the port. If you can, try starting and running at wide open throttle. If it runs fine( a bit loud, so wear hering protection), then you have a plugged or partialy blocked muffler or spark arestor. Sometimes rich mixture can cause excessive carbon build up.

Hope this was helpfull.

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.

Ryobi gas blower idles fine when i push the throttle it stalls


some carbs are not adjustable,check your air filter first to make sure its not rescricted and also a new plug,make sure your fuel is fresh,now if you do have adjusting screws,most have plastic caps on them with preset adjustments locked in,you will have to remove these caps to adjust,they need not be reinstalled,Hope this helps

Blower wont run at full throttle


Start with the spark plug it is the easiest.

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.

Good Luck
