Question about Garden
All 2-strokes love to run rich when cold thus full choke till it kicks, half choke to start and leave on for 5 seconds high rev's to warm & lubricate, then no choke to run. Restart when hot is 1 pull full choke (you are now flooded) & then no choke til it starts. Try it. Works every time on all of my 2-stroke engines.

You may wnat to inspect the intake manifold/boot that mounts inbetween the cylinder and the carb. Also, the impulse tube that comes from the bottom of the cylinder to the carb manifold or carb itself. Sounds like you are running a lean condition. You need to locate the source very quickly, or continued operation will permantly damage the saw. I have listed a few other things to check.
Please let me know what you find. rwvanlue
Basics to check:
1) Spark plug - brown or dark brown - OK
a) is it carbon or fuel fouled (black and carbon deposits)
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
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:
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

Ensure air filter is clean. Foam elements can be washed with hot water and detergent, squeezed dry in a cloth and re-oiled with a teaspoon of engine oil spread through the foam. Paper elements can be cleaned with compressed air blown from the inside of the filter but ideally should be replaced.
Check fuel lines aren't kinked or blocked restricting fuel flow.
Ensure fuel filter isn't dirty. This is probably located at the end of the fuel line in the tank.
Check the throttle cable is actuating the throttle plate in the carburettor.
On some machines when the machine is revved, the choke is knocked off automatically, make sure this is happening ok.

Make sure you have control set on run,not choke or start. Check spark aresstor by removing exhaust cover and cleaning screen of carbon and oil build up with spray carburater cleaner and fine wire brush.Also remove gas cap and make sure that vent hole in cap is open.Otherwise it can draw a vacumn after being ran for awile and be very hard to start.One last thing is make sure that spark plug gap is correct and that there are no hairline cracks in porcelin insulation. Best of luck. Thank you.

SOURCE: saw stops runing when it
Couple of possibilitys here, when it starts to die slacken off the fuel filler cap, if it then picks up again it is a blocked fuel tank breather, the other possibility is the ignition unit breaking down when hot, the only answer here is to replace the unit.
