You might try an RH S.U. needle or and RG Which is slightly richer. These are
a lot leaner than the ones used for racing which are RB RC nd RA. In my
famous ntoebook I have a lot of the S.U. needle info. I can scan a page and
send it if it will help. I'll be adding this to my new revised upgraded
Handbook that I plan to have available as a download within a couple months..

Thanks for locating the spreadsheet, I will get a copy so I can
compare it to the SU charts that I have. The ones in Kas' book
should give a starting point. This is for a TR250 street car, which
I want to warm up but maintain an overall stock appearance. I want
it to be like it would have been if not for the emission
requirements. More or less like the 128 mph demonstration car Kas
did back in the day. I've taken the compression ratio to 9.5 and
put in a longer duration cam (BP270). I have yet to do anything to
the carbs, so I'm still running the fixed needle Z-S. I want to
stick with Z-S to maintain the stock appearance, but will need to
switch to some adjustable ones or make these adjustable (see Buckeye
Triumphs).

just a reminder that on page 110 of my book the "Handbook" there
is a chart of the needles we used with great success in the
1.5" carbs.. These are STROMBERG needles. Lots of number to
compare. By the way that is .006" shim stock you need to use an
S.U. needle.
