That's pretty interesting about your GCR regilations from 1969. I did the
homologation for that year for the SCCA and the only thing allowed on the
TR-250 and the TR-6 was P.I. They would NOT accept a carbureted version for
classification. They NEVER allowed Webers or other carburetors as long as I
was running which ended in 1972.
If you have the choice though, go for the carburetors of any kind rather
than the PI.
