Hi Pete,
Thanks for the reply..

I have tried to look back in the engine forums to see if there are any mods that stand out.. But as there are a few threads to look through its an endless task.

I thought that maybe there was a harden group of rev heads that grind, shape and mill out there and that they may join a Modification Forum.

I am in the process of rebuilding a OS 46 and I am going to do some porting etc and just wanted to make contact with others that have done it.

Regards
Phillip
