Thankyou Simon, you saved me from what could have been an expensive mistake when I finally get round to firing the engine up. Regards Don.

I'm putting together a 1949 KG twin from a pile of bits. Can any owner tell me, when looking at the 2 unions at the rear of the engine which is the oil inlet and then obviously, the return to the tank. I cannot find any reference to the flow directions and would rather not take a 50/50 guess. Hoping...
