Just picked this up for $20 today. Fired cold on third pull on choke, started on next pull with choke off, idled great, revved well and held consistent RPM at idle and WOT, no dead zone on acceleration. Chain stopped immediately when dropping to idle, so clutch is in great shape. Manual oiler fully functional. Even some life left in the chain.
I guess I thought when I heard about it that, as a 3.7 hp it'd be a Poulan 3700, but is it older than that series? Doesn't look quite right to me for a 3700. Sure has been well cared for.
That there is a ROPER 3.7.
