Got it running now. If you read back I did rebuild the carb.
From everything I've gathered problem was caused by a not only bad ration fuel mixture but also debris in the fuel. Replaced spark plug, fuel lines filters rebuilt carb and replaced air filter. Also reset the ignition coil to within spec.
Got the idle adjusted and the saw is running like a champ, like it always did before 'mikey' borrowed it.
Scott the owner of the saw is a very good friend that has been there for me in more ways than I can count. To be able to fix this problem for him did way more good for me than it did for him.
Thanks guys.
