I've just been looking for a parts breakdown for a Poulan 2550 chainsaw..I've wasted an hour looking at various different sites , trying to find fuel lines/filters inside the fuel tank..I recently acquired a little used Poulan 2550 chainsaw that was " Hard to Start"....You Betcha!!.. After draining out the fuel tank , I found nothing inside the tank but air..No lines , no filter...Surprising it was a hard starter only missing that stuff.. When I went online to find what's supposed to be there , I was led in circles , always ending up at the starting place...That just "Jacks my Jaw" to no end..Is there anyone with better computer skills than what I have to find a source of illustrations for parts..On Poulan.com , there were about 7 or 8 different 2550 listings , but I couldn't access them.... Circles again..They probably will let me look up parts if I had a part number...Here we go again...How do I find a part number????
