Default Need parts for OS 20 1971 inboard engine

I have an OS 20 Marine engine with an aircraft exhaust circa 1971.
I need a gasket kit, idle screw, mixture screw and exhaust strap
for this engine. I know it is old and not competitive but I love restoring
older boats.

Anyone help me, Regards Brettos.

That's going to be a tough one considering its age. There are some people that do specialize in old parts for out-of-production engines as I've seen them at places like the Toledo show in the swap meet area. That doesn't do you any good living where you do though. It's getting harder to get a lot of parts with the manufacturers constantly updating their engines. I bought one last year new that I might be out of luck on as it's been discontinued already. Another engine I've gotten lucky on, finding some parts at a LHS and on eBay.

Thanks Ron, I will check those spots and keep my fingers crossed.

Someone told me that there is a gasket glue or paste that can be used to seal the C/Case end.
Ever heard of this before???

Also, could'nt I use any old replacement screws for idle & mixture or are they specialy tappered screws???
I was thinking of using stainless hex heads for a nice look.

What do you think???

Regards Brettos.
