baseline carb settings

evening people , what are your baseline carb settings for the p11 ? the burlen site gives lots of options but i just want a rough starting point , main , pilot , needle jet sizes , needle type , clip position etc
how do people count the clip position from the top or bottom ? so 3 position would be top or bottom ?

thanks in advance
andy

The Roy Bacon Norton Twin restoration book states:
1967-68 P11
R930/7
L930/8
Mains:[HASHTAG]#250[/HASHTAG]
Pilot:#25
Slide:#3
Does not state position of needle so start at the middle groove. two ring identifier type.

Needle Jet: 107 but I would go for the 106 for your base line.
Set your float height first and get them even and close to 0.080"-0.120" from the top lip of the float bowl. Use our forum search engine and tech section to get it close.
Cheers,
Thomas
