When the carb was "rebuilt" Did you pull out the screen and clean it out and also did you pull needle and diaphragm out and clean it out good, because if the needle is not working or the neoprene tip is swollen your needle adjustment will be out of whack,sometimes carb cleaner will make it swell up to where it won't open enough to get fuel through it....suggest you replace the needle and adjust your height of the tab to flush with the body of carb and make sure you have a good diaphragm in it along with new check-valve diaphragm, then make sure your primer is hooked up right ..it should be pulling fuel through the filter to carb and through carb and back to tank,your problem is definitely in the fuel system, keep trying different things you will figure it out

Fuel lines could be collapsing from being soft, mush from ethanol in gas, possibly you have wrong carb kit, or something put together wrong, fuel lines reversed, double check everything then make sure you exhaust screen is not plugged, cause this will do same thing.

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...

No fuel in primer bulb on my echo PB 2100 blower


The primer bulb pulls fuel from the carb into the bulb and dumps back to the tank, so either the tubes are not connected too the correct conections on the carb, or there is bno fuel getting to the carb from the tank ( fuel filter ) or if the primer is on the carb itself there in a red one way valve under the bulb which maybe faulty.

Pb 755 runs but when you open it up for more power it will not give it to you charge fuil filter ,air filter new spark plug new could it be the rings


Does it still run the same or bog out? Look at the fuel line going into the carb and see if it has bubbles in it. When you pump the primer you will see them moving in the line. If so then replace the line where it is leaking. It could be coming from the carb to the primer. Then it is coming from inside the carb. Needs to be rebuilt or at least cleaned. Take it off and slowly take it apart careful not to damage the gaskets. And you can clean it and put it back together. Or get a kit. Probably 15 or so. Here is a site where you can get parts and a break down of it. Good luck.

I have a Echo PB-260L Blower. It starts fine then gradually loses power sometimes completely shutting off. I have replaced the fuel filter spark plug air filter and have cleaned the screen.


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.

Runs rough and only on full choke


Did you relpace the inline fuel filter? they need replacing every year due to fuel addtive required by the feds. Try that first then the primer bulb check valve could have dirt in it with the air cleaner off look into the carb port and press the button three or four times, if you see no fuel then replace the filter first then pull the gas bulbp apart and clean.

A pb-200 blower won't rev high enough. I have 2 blowers and one won't rev as high as the other. rebuilt carb. changed fuel line. adjusted carb. changed plug and air filter. new gas mixture. checked exhaust...


Does it seem to have about the same compression as the other? Does it have equal spark? Any excess friction when pulling it through? When you had the muffler and carburetor off, did you notice any piston skirt damage visible through either port area. How about carbon build-up at the upper piston-side of the exhaust port--common on 2-strokes running heavy oil/fuel mixes. Worn/leaking crankshaft seals?

guarantee exhaust is clogged maybe not muffler but exhaust port pull muffler off check screen and muffler then look into exhaust port usually rectangular port is closed down with carbon pull starter slowly to lower piston then scrape out carbon with screwdriver clean as good as possible then blow cylinder out make sure to get all pieces of carbon out reassemble should run fine
