Have you checked eBay? I found a couple of service, owner and parts manual combos for as little as $12.50 shipped.
+1 on Tru-Fuel. I resurrected a 25+ year old Poulan model 2000 this week and it fired right up on the 40:1 stuff.
I run the 50:1 in my Stihl MS290 doing hiking trail maint. in a state park. There's nothing so frustrating as hiking 5 miles with a heavy saw and have hard starting issues. NEVER a problem with the Tru-Fuel.
