start off, my car, an early BN1, #598 was burned up in the Paradise fire a=

rust worthy person. Well I'm having problems with the car. Up to 2500 RPM,=
it runs great! When I can get it up to 3200 RPM it runs great again, it's=

=C2=A0=C2=A0=C2=A0I was told the carbs were set up a little rich. I leaned=
