Title: Barrel type?
Post by: spyke on 05.10. 2009 13:21

Hi chaps,

Do all A10 barrels have the little cut outs in the top fin?

Cheers Spyke

It would be darn difficult to get the rocker box on and off without them.

Oops! Spyke stated cutouts in the top fin of the barrels; I misread and was thinking cylinder head.
The spares book shows such cutouts. Their purpose is to provide clearance for the exhaust pipe finned collar.

Early Rigid/plunger barrels don't have them.
