RE: OS .40 engine question
Me three!
I've bought myself (few months ago now), was a brand new in box O.S. .40FSR off eBay. Paid $120 or so for it but I cant believe how WELL the older engines run. My engine was first built back in 1975. Start first go everytime and could run all day long without a hitch. One thing to bare in mind is that, your should always run abit of Castor oil in your fuel through them. As these old timers will love you for it.
$40- bux is a bargain and if i was you, I'd buy it. You have nothing to loose and chances are, the person selling it to you hasnt got a clue about value. Wont be dissapointed with O.S. like someone said earlier. All my engines have been O.S. and I wouldnt change for the world.
