GalenB,
Before you purchase that OS 7D carb, I suggest you call Perry Pumps (630-858-3160) and ask them about the best pump / carb setup for your engine. They are very helpful nad knowledgeable. I'm betting you can purchase their pump and pump carb for about the same $'s as the OS 7D will cost you.
I put their pump and carb on my ST 2300 and have had great results with it.
The pump is supplied with a pressure fitting that is installed into the crankcase by drilling and tapping a 6/32 hole (usually in the center of the engine back plate). The pump instructions explain how to do it.
