Craftsman chain saw won't start!

I have not even a year old Craftsman chain saw, 2cycle 42cc motor, 18" bar. It worked OK until now. Since day one, after it got hot from few hours of use it wouldn't start. It would always start the next day though. I used it a LOT last night for about three hours. It died yesterday and wouldn't start. I couldn't finish the job !

This morning I go finish the job and it won't fire! I spent an HOUR trying to get it to run. I checked the air filter, which is clean, checked the carb which is clean and getting fuel. Checked the spark plug which sparks. It has brand new gas with 40:1 mix.

The only thing I can think of is that it doesn't have enough compression to start.

Any ideas???

 

Most common mistake: Killswitch haha. Everything sounds right though. You have taken the carb off and cleaned everything throroughly?

 

All new mowers/ saws etc are built with the carbs so lean they hardly run.
I've had to drill my mower/ saw /weed whacker carbs to get to the adjustments just to get them to run ok. Not an easy thing to do.
My suggestion is to get a new plug. put 4 or 5 drops of fuel down the plug hole. install the plug and try it.

 

I've had a hell of a time the last few years with the ethanol and small engines. The ethanol plays hell on the carbs, sometimes fuel additives help.

 

???? That never happens.......................................

 

usually this

 

Unfortunately, I know a few people that just don't have good luck with Craftsman chainsaws. My father in law seems to always be battling to get his to start.

 

I put fuel in the spark plug hole. Same result. Won't start not even sounds like its attempting to start...

I think even if carb would be clogged or bad, with fuel in the cylinder it "should" start and run for few seconds.

I think this saw is toast

 

Now even if the fuel mixture wasn't exactly right the saw should still start right?

 

try takin the plug out and given it a few pulls. is there a fuel filter in the gas tank?

 

Already did that dont know if there is a fuel filter...

 

It should at least try.
you have spark you said
air filter not plugged
does it seen to turn over easier than before ??
could have seized the rings in the piston for no compression.

most of the crap now is use and throw away.

 

when it died, what happened exactly?

 

Can't notice much difference in how hard is it to pull... I would say its tad easier...

Yes good point I should have bought a better quality saw... I thought that if I use it once a month it would be ok... Guess not.

It has 2 year warranty, I will take it to Sears service center and see what they say.

Funny thing is that in the morning I tried to start it and it fired. I shut it off, hour later won't start at all, not even sounds like it tries to start.

I am thinking even if it was straight gas and no oil, it should still start, just wouldn't run very well and would burn up the engine... BUT I put oil in the gas...

 

piston could have scored the cylinder walls. if the its a little easier to pull that might be the case. take it to a saw shop and have them look at it?
