Sthil 038 chain saw

This is a great saw but now when starting I can pull the cord a few times with ease then on about the fourth pull it wants to take your arm off. It is like it is getting stuck. then after I pull the cord again it is ok and again it will get stuck. (Hard to pull) Anyone have a fix to this problem it has never done this before.

take the spark plug out and pull the cord sharply several times and then reinstall the plug to see if that makes any difference. I'm thinking there is a bit too much gas and/or oil in the cylinder.

I have done this and again after a few pulls of the cord it is fine then it wants to take your arm off again. I have changed the spark plug cleaned air filter and still the same. Is there an automatic compression release on this unit and if so where would it be located. Could it be that it needs cleaning?

I don't think that saw has one. Is the spark plug wet when you pull it out?

Slightly. After I refuel and try starting it again it just does not start , after I run out of gas. It is firing I tested it with a spark light.

When you say it tries to "take your arm off" is the saw hanging up or is it kicking back? The latter could either be the flywheel key has sheared = timing problem or excessive compression due to carbon build up.

If it's hanging up it could be the starter cord/rewind or the rod bearing = bad news.

No it is hard to pull after a few pulls on the starter cord. The first couple of pulls it is fine then it is very hard to pull and after two or three pulls this it is fime and normal again. the saw does run. I have to sometimes use starter fluid but it runs fine. It is the starting. I am going to remix the fuel and change the fuel filter and see what happens.

If, when it's running it doesn't lock up or put out a lot of extra noise, I imagine you have a problem with the starter rewind. Take that thing off and turn the engine over by hand and see if it turns over a number of times without any problem. Do this with the plug out.

Smile stil 038 chainsaw

I have it running again. I cleaned the carb. and the cylinder with gumout and alot of black carbon came out of the cylinder. Pulled the cord a few times with the plug out and then emptied the liquid. Changed the fuel and it is running again. Now I need to order some extra parts. Any good sites out there? Thanks for your help...
