Do you think the 21D is too big?I have one.. NIB.. when we OS stared on this motor we asked for a 320 to 340 bore on the carb.. and a standard plug..
BUT.. they did not move that direction.
To me.. those.. the carb bore in particular needs to be changed.

It is very hard to find them. They are popular for the Endurance (multihull) racing in Europe. Have you considered off road engines? I have been using OS 21 XZ Spec 3 for a while, and it is a nice engine for sure.Joern, where can someone buy that motor? Having a hard time finding it
I have one and I’m not impressed with it, there are in my opinion lots of better engines from CMB, Nova. The carb is too big, I changed mine for a MAC 21 carb and the engine performed a lot better but after years of playing with it just can’t get it to perform like all the rest.

I have the outboard version of that engine that Rody Rome sells. On my Vision running the 21D carb and a gadget craft carbon pipe, I had no issues with throttle ability, wasn’t finicky to start on the stand, and ran like a scalded cat.

For me it has been great, engine is screaming like a stabbed pigInteresting Joern with the 21d on the 46 response would be crisp..how is top end though?
