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

Won't start


Are you getting spark on plug? Check to make sure wire is connected to plug, if still not starting. Is fuel getting to plug? Remove plug an see if its wet. If its wet it could be flooded. If not fuel lines are common on saws, tank in is a major problem it cracks an need replacing. Have you checked the on off switch? If it still wont start, carb is more than likely the problem. Remove it an get a rebuilt kit, they are cheap, carefully remove all parts clean out all orifices even small ones with a piece of brass or steel bristle from a brush, use carb cleaner to clean the parts, carefully put it all back together an it should start. That is about all there is.

Ran last year, won't start this year. Changed fuel and replaced spark plug. Checked spark and attempted to start with battery and tried with pull cord but no start. pulled plug and it had fuel on it so...


It might have tipped over on its side. Look at the air filter, if you see oil or gas on the filter then you might have to remove and clean the carburetor. I would start by cleaning/replacing the air filter and trying it again. If its getting fuel and the spark plug works then the only other side of the fire triangle is air.

Unable to start my 155BT blower. Have changed


Is the new spark plug wet? If not, the machine is not getting fuel (fuel filter, carb, etc.) If the plug is wet, you may not be getting spark (bad ignition module, short in switch/harness, bad plug (yes it does happen with even new plugs)), or flooding due to incorrect starting procedure or clogged airfilter. Stale fuel can also cause an engine not to start as it lacks volatility. If in doubt, take it to your local dealer.

Homelite ut o8107 blower 25cc will only idle


Hello:

Have you Removed the Muffler and Checked the Exhaust Port and Muffler for Carbin Restriction?
Remove the Muffler and Start the Unit. If the Operates Correctly, then the Spark Arrestor Screen is Clogged and the Muffler/Screen Requires Replacing.
Make Sure the Exhaust Port is Not Restricted Also.
Hope this Helps.

Good Luck

Respectfully
