Find the fuel air mixture screw located by the carb and turn it so the moter starts to slow down then turn it so the blower runs smoothly this should keep it from dying out

Echo ES210 Blower will not start


Since you are getting spark from the plug it sounds like a fuel problem. I would check all the fuel lines and make sure they aren't plugged and ensure the filters are clear.

Troy-Bilt Hand-Held Blower dies when warm and throttle wide open

Good job.
A couple more things:
  • Replace fuel filter, it's in the gas tank
  • Check and clean the Spark Arrestor screen at muffler, when they plug up, it's a major restriction to exhaust gas flow
  • And check and adjust High/Low screws at carburetor, video attached.
  • And clean or install rebuild kit for carburetor
Good luck...

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...

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.

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.

After getting hot the blower will blow very hard at full throttle and then loose power and then back to full throttle after 2-3 seconds. It does not do this when it first starts off cold. I have relaced...


Basics to check:
1) Spark plug - brown or dark brown - OK
a) is it carbon or fuel fouled
b) is there spark

2) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated
3) Check cylinder compression



Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

I have a Echo PB/251 Gas Blower which I recently starting having problems keeping it to run. I have to keep the choke on to let it stay at a fast idle. I have taken the carb apert along with all gas and...


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.

Hope this helps,

Only runs on full throttle


Are you saying full throttle, or full choke? if full throttle, you should be able to set the idle up. the idle screw will be the one when you give it gas, it will be the screw on you'r throttle linkage. If full choke, maybe the spark arrestor is plugged. You can remove it by removing the muffler.It would be between the muffler and cylinder head. You don't need this to run.I hope any thing I posted will help.
