On your poulan, check if there is an crankcase pulse line running from the crankcase to the carb. If this is leaking or deteriourated it may be the problem. Also check for obstructed fuel line and pickup. If those check out ok, it may be in the ignition system, Check continunity through the points, ohm test the coil with a multimeter. If the points are bad use a megafire module instead of the points (avalible at most lawn mower shops) If the coil is bad, try to cross reference it with the coil on a another saw, or shop E-bay.
I came across this question by accident, I am in the market for a partner 85 cc saw, not running is ok. my email is
jllinenfelser@msn.com. Email me with more details about your poulan as it should not be to hard to get running, and also if the partner is availible. good luck Jim
