simple enough prob - go to any local mower repair shop or hardware store and buy the small bottles that you mix with 1 gal of gas - all 2 cycle engines can use it - it makes life so much easier-

SOURCE: My leaf blower will not start, It keeps flooding

To start: turn the choke off, hold the throttle wide open and crank. You have a carb problem but this should get you going. John

Please rate if this helps-

SOURCE: poulan pro leaf blower doesn't start

As long as it has fire, all you need to do is:
Check the fuel lines for cracks/breaks. If this is o.k., then you will need to disassemble the carburetor and spray with carb. cleaner. Use a Den Tek Brush,
(http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152), to clean the small portals in carb. Make sure the small screen in carb. is free of debris.
If you still have trouble after this, then you will need to buy a carb. kit and replace all appropriate parts.

Blower vac vac tube will not stay on


fuel starvation
check the inline and fuel tank filters
and also the tank lid has a small gas presure release on it
this may be blocked causing a vaccume
try to also replace the paper air filter and also the spark plug
clean the fuel out and replace it start it and drain the carborator
with more fuel to run it out
if this fails to help
you may need to clean the carb

i dont think its anything serious
although it could turn out too be a faulty ingition pickup coil
{feeds the spark plug with juce}

Craftsman leaf blower wont start


The air gap for the ignition coil core to flywheel is adjustable on some engines and the gap does vary.
On a Stihl, I used a matchbook cover first, then doubled it and got the engine to start. That amounts to 8-10/1000ths (0.008-0.010") as measured with a digital caliper after-the-fact.
I'm troubleshooting another engine currently from a McCulloch Airstream IV that only has ~12 hours and no spark but the coil measures roughly as it should; around 1K Ohms. Was surprised to find the company went bankrupt in '99. Another one killed by Asians and fairly poor design.

CRAFTMAN LEAF BLOWER WONT START


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

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
