OS engine Parts
 

Anyone have any idea where one might find a used block for an OS 61 FS? My buddy distroyed his trying to remove the front bearing (force never works).

You may have better luck buying a complete used engine at a online auction.

Bruce,


There might be a better option, for less dough.

An [link=http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=8988]ASP S.61A[/link] from HobbyKing.

It is an FX clone with a true ABC P+L (unlike OS' ABN/L), so it will last longer.
It is not an under-square engine ('Long Stroke') like the SF was, though.

Thanks Dar,
I should have clearly spelled out 4-stroke, forgot the 2 stroke FS series..........Getting old I guess.
Thanks,
Bruce

You did say it was an OS 61FS, Bruce.

RE: OS engine Parts
 

Oooops!

I missed that... I thought it was the SF you're talking about.

The [link=http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8985]FS[/link] is under $115.

Try to find a used OS at that price.

Oh well, There was a fellow who had lots of old parts on RCU years ago...got a case for an OS 60 FS (PRIOR TO SURPASS) for a fair price. Just though it was worth the effort.
Thanks,
Bruce

The two-stroke OS engines have the letters after the displacement size, such as OS .61AX. The four-stroke OS engines have the letters before the displacement size, such as OS FS-91, now out of production, I believe.
