Old Craftsman Saw

[crepitus]

I have an old craftsman saw. It used to run great then the fuel lines rotted out. Replaced them and it ran fine for a year. now the saw screams like its very lean. no matter what i do with the high end adjustment it will do the same scream and die. what could be the problem? what controls the rpms on these things?

Maybe you have another cracked line...or one of the new lines is coming off?

Sounds like a vacuum leak.

thats what i was thinking. i checked the carb and tightened everything up. where else could it be coming from?

Bad pulse line/pump needs a rebuild kit. Have you checked your fuel filter?

fuel filter has never been changed.

You might want to change it. If it can't flow enough fuel it could make your saw run lean.

I have a couple of the Roper 3.7 CI Sears saws. They have a link connected to the trigger that pumps the chain oiler (I think?). One of mine was hanging up the throttle linkage and it ran like the idle adjustment was cranked in. Might be worth a check.
