Thanks Paul...I'm glad I checked.

Quick question:

Are the early short splined mainshafts interchangeable with the later long splined ones? I know the clutch centres are different: the later one has the internal boss to cater for the long splines on the mainshaft, but apart from that, can I use either?

Having bought a '46 single-port VH engine from Dave Owen a couple of weeks ago, it prompted me to look at the carb on my existing '46 2-port VH Red Hunter.

Yes they are....yours is the one with the long splines and the boss on the inside, so quite common. I'm sure Geoff will have those.

As long as the splines are OK, its an easy fix and no need to dismantle primary chaincase. I always use Loctite on this nut, as well as the tab washer.
