Yeah, the recoil mechanism is totally done. The guy I got it from tried to fix on it, I guess the clutch doohickey is frozen solid, he pulled the string, it grabbed the rope, pulled it back in, and snapped it off. Then not knowing the issue, or how to fix, pulled out the spring and spool. S
o the spring is history, and the spool is chewed up. Fortunately, I have a 3.5 b&s that's toast, but the rewind set is good, so I'll put it in the snapper, carefully! I remember trying to "fix" mine as a kid, and that spring shot out, took forever to get right. Like I said though, I'll keep it, even though I don't need it. Too awesome to sell!
So I didn't know you could date b&s engines, googled around, mine's built 5/1/87. Things purtnear old as me!
