    idle picks up when saw is layed on its side

    I'm cleaning up a 041 AV Farmboss for a friend of mine. Cleaned the airfilter, dumped the old mix out and put fresh mix in, checked the plug, checked compression (165 #). Popped after 5 or 6 pulls, fired after 2 more. It idles pretty rough. In the upright position, the saw idles way too slow, when I lay it on its side, the idle picks up. Do you guys think this is carb related or crankshaft seal related?

    Check your carb block gaskets... and the block is tight. Very common leak point.

    Seal leak - if it is that, then check your oil pump seal carefully...

    Carb - bad metering diaphragm or leaking inlet valve seat can also do this.

    Well.....here's another option.....Are you sure your finger isn't on the throttle when you're turning it on it's side?

    Yes .....it does sound like something is moving causing more air and or fuel to be given to the saw.

    this is a long shot but pull the fuel cap and see if the filter is dropping to the bottom or new bottom when its on its side
