Joe,
Each day this MCA website gets more and more interesting for the development of kowledge on all Wallis and Massey subjects, it is such a reference of information for collectors of the future, so I hope the MCA committee has now understood and appreciates the NEED for this information to be retained with the relevant back ups made so it is never lost.
Well Joe I am now going to have to take a hand hole cover off K 11823 tonight and refresh my memory of the cam followers in there as I don't recall seeing this before, interesting it is not in any of the parts books etc.
Time and patience is of the essence here so keep squirting plenty of penetrating fluid around , walk away and come back a few times, a bit of heat from the torch might just help and a few taps here and there could loosen some of the rust, I would try some of these measures before thinking of cutting up the camshaft.
Interesting also seeing the primers on the inlet manifold, never seen those before going right into the cylinders, I like the cork plugs someone put in the oiling system, shows it was not a great success.
Keep us posted of progression and you need a trip down to Oklahoma to check out the features on the oldest known surviving Cub Jnr so far, wonder if it has all these??
Malcolm.
