Mike,
Sorry, nothing at hand as it has been a while since I played with
the 1.5" carbs on the 2000cc motor. [This was really a 510 project,
but pretty much the same as putting the R16 carbs on a motor that
has been stroked to 2000cc].
One place with a ton of good information is Julian's SU page:
http://www.jetlink.net/~okayfine/sutech.html
Jets remain the same at 0.090" Needles... I ended up "richening"
a set by sanding mid range on the needles, so never had a part
number. Years back I did a write up on a simple O2 sensor for
the exhaust pipe... just to make sure I wasn't running lean.
Cheers,
Tom
