Question about Garden

Trying to get my Poulan leaf blower to run again. It suddenly quit. Have checked out fuel line, filter etc.-all ok. Took apart carb - no luck. It will run for a short burst if a add gas directlt to cyclinder via spark-plug port. In short, it appears to not be getting fuel-rubber diaphragm in car looks intact. Ant other ideas?

Open the carb back up. Directly under the inlet needle you will see a mesh screen. Remove and hold up to light. If it's clogged (and it's HIGHLY likely it will be) take the carb to a reputable dealer and buy a rebuild kit for it (not simply a diaphragm kit, the screen isn't in that one).
About 10 bucks for most kits.

Hope this helps.

Primer bulb won't pick up fuel, bulb, lines, filter seem ok. bulb creates pressure in the fuel tank when priming but no fuel will enter the bulb.


Hello Steve,
Your problem sounds like an internal problem inside the carburetor. I would first check fuel filter inside tank, but if that's ok, I would remove and clean carb. If you don't feel comfortable with this bring it in to a repair shop. Good luck. Hope this helped!

Gas blower engine surges and shuts off when engine gets hot


check your fuel lines for cracks, could be sucking air or could be your carb needs cleaning, make sure you clean the screen inside the carb, if you run it with the choke on partially does it smooth out and quit surging, if so it is definitely a fuel problem. Hope I helped you. 2StrokeJim

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.

Starts but will not run


its a fuel issue. check fuel lines and fuel filter. If fuel lines are discolored or brittle or if filter has become unattatched from line- the fuel lines need replaced. Then carb needs adjusted ( turn low speed jet out 1/2 turn) or rebuilt

My weedeater leaf blower never gets up to its' old speed. Runs about 1/2 the power. Tried a new spark plug and air filter. New gas didn't help.


Basics to check:
1) Spark plug - brown or dark brown - OK
- aluminum or silver - piston/cylinder scored
a) is it carbon or fuel fouled
b) is there spark

2) Compression - 125 to 150 psi

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

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
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
5) replace gaskets/diaphragms
b) use a spray carb cleaner to clean jets, holes, and body of carb

Poulan leaf blower won't start


Check the fuel lines for cracks/breaks. If they are o.k., then:

You will need to disassemble the carburetor and spray with carb.cleaner.Make sure the small screen is free of debris. (Should be able to see daylight through it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance on:
1. Fuel line replacement or
2. Carburetor kit replacement

Just let me know.

Weedeater will not start. was running, shut it off and then will not crank. I have checked all the obvious(spark plug and wire, has good fire, fuel filter and lines,took apart carb and cleaned good) still...


Pull the spark plug after pushing the primer bulb and cranking a few times...if the plug is "wet" (indicating fuel is present in the cylinder) then the next step will be checking the compression...compression should read above 90psi (preferrably 100-125psi)...if compression is below 90psi, the most likely culprit will be a stuck piston ring.
