I cranked my 440 last night to cut a small oak. I let it idle for less than an minute and it cut off. I cranked it again and after a second or two it cut off again. Pulled and pulled, but no start.......Spark Plug????
I changed the plug and the saw fired to life. I am surprised that I fouled a plug after having done so little work with the saw...probably 5-10 running hours max. It was exceptionally damp yesterday (visible fog and light rain), and the last half hour of running was at part throttle trimming bushes in the yard.
One culprit may be my low speed adjustment. When I adjust it I find that the leaner I set the screw the better the saw runs, but Im afraid to set it full lean. So I go lean to best idle, rich to rough idle and settle for a little rough on the rich side.
