Valve Clearances T16 Mercury engine

[andrew honychurch]

Looking through my TM on the T16 I see that it recommends inlet at 10 to 12 thou and exhaust at 14 to 16 . Before I go to the effort of doing this I wonder whether anyone has any comments on these clearances given modern fuels and whether that may effect these. Also, I need a few engine bits and bobs, studs, head bolts, a valve , gaskets, rings etc. Can anyone make an recommendations of suppliers either here in the UK or abroad? thx chaps
