    The saw will only idle when on its side. Flywheel side up.. Is that an indicator of which seal may be bad.??

    Thanks.!!

    Probably the clutch side, but you may as well replace both. Out of 3 024/026 saws I have with scored pistons, 3 have clutch side seals bad. I have been using a small pin punch to knock one side in a little and then using a tool like H 2 H has (see thread: http://www.arboristsite.com/chainsaw/215891.htm#post3975677) to pull on the opposite side I punched in. Don't drive it in too much, just enough to move it a little. Good luck!

    Are you saying it idles to high, or will die? A bad seal will make it idle too high, and you can't bring it down. In my experience, I've seen the flywheel side be the most problematic. Replace them both if in question.

    Had a similar problem with an 024 recently. Replaced the flywheel side only as per Brad and others experience...ring, ding, ding, idles fine now. :msp_thumbsup:

    *Should start a seal trading thread. Trade you a right for a left...:hmm3grin2orange:

    The seals in it are new. I thought maybe I installed them wrong. Actually everything was replaced when I rebuilt it. I didn't rebuild the carb and was just wondering if it would cause it to act that way. I've never rebuilt a carb, but I'm assuming its easy.?

    A vacationing penguin is driving his through Arizona when he notices that the oil pressure light is on. He gets out to look and sees oil dripping out of the motor. He drives to the nearest town and stops at the first gas station.

    After dropping the car off, the penguin goes for a walk around town. He sees an ice-cream shop and, being a penguin in Arizona, decides that something cold would really hit the spot. He gets a big dish of ice cream and sits down to eat. Having no hands he makes a real mess trying to eat with his flippers. After finishing his ice cream, he goes back to the gas station and asks the mechanic if he's found the problem. The mechanic looks up and says "It looks like you blew a seal."

    "No no," the penguin replies, "it's just ice cream."

    Some people can remember jokes, but I'm not one of them. Except that dumb old joke for some reason! Naturally no one around me wants to hear it anymore, so it's always good to find some fresh blood to use it on..
