I have an echo pb 265l leaf blower. It starts great and idles great. After a few full throttles, it loses power. Already took off the spark arrestor screen and threw it away. It was clean. Still has same problem
Re: I have an echo pb 265l leaf blower. It starts great...
If its a two cycle engine it sounds like its loading up on fuel.. Need to lean out the fuel on the carb. Not much or it will be to lean an stick the piston..
How do you lean out the fuel on the carb? Do you mean clean? Do you mean lean meaning use less oil in the mix?How do you lean out the fuel on the carb? Do you mean clean? Do you mean lean meaning use less oil in the mix?

check the ignition wiring from the switch to the, ignition module and plug, use a volt meter to check the circuit. If all ok, look towards the ignition module fault.
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
Check the exhaust port upstream from the muffler and make sure it is not restricted with carbon. Mine was less than half way covered over with carbon. Scraped out carbon, checked muffler and screen(ok), back-blow the fuel line harness including the fuel filter and fuel tank vent and took carb apart and blew out all passages, not replacing anything and now runs fine. Would not rev past high idle before. Be sure gas is FRESH and mixed at 40-50 to 1. Hope this helps.
Check the muffler and/or spark arrestor screen in the muffler outlet pipe and also the engine's exhaust port behind the muffler. These are prone to carbon-clogging and the engine cannot "BREATHE" enough to reach full throttle. If all-clear in the muffler, go back in the carb and locate the inlet screen directly opposite of the inlet needle. Carefully pull it out with a pick and hold it up to a light source. If you cannot see thru it, replace it. This is another, (less) common area of obstruction.
Had the similar problem- start with removing the exhaust intake plate 1st--- clogs with super fine dust initially then larger particles... Mine was completely clogged- cleaned er' out now she blows like the wind!
