<VV> Main jet size

[J. R. Read]

Guy is correct on the sizes that we used.  We did a carb rebuild session 
(about 5 of us together - a dozen or more carbs) some time ago.  Apparently 
his memory is better than mine even though he is six months older than I.

I just checked the "spare" carbs on the shelf from that session.  I had 
marked on the outside of the carbs what size jets were installed and Guy 
nailed it on his message.

I do not know if a '69 engine should be different, but I suspect not. 
Certainly 60 jets would be TOO large.

Later, JR
