[Fot] Zenith-Stromberg needle specs

[Larry Young]

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).
