Your engine is very lean. Tell us what needles are in the SU's.

I've not overhauled or disassembled the SU's. It's a 1967 model year and I'm *certain* that the carbs are original to the B18 that I pulled from the car and that the engine/car had a true 166k miles on it before this engine swap.

Is it known, with any certainty, which needles were installed stock on 1967 B18 equipped amazons. It was/is a sea-level California car, if that matters.

You need more fuel before you stomp on that engine.

Even though I was certainly taking it easy, I'm going to try and answer some of these questions that came up before I drive it any more. Is new needles a must, or would richening the mixture at the carbs by a couple flats be a safe-enough intermediary measure to get her back on the road? I still haven't decided what to do re. carburation- whether to try new needles in the SU's, whether to send the SU's out for a proper rebuild, or whether to invest my time and energy into the set of rebuilt side draft Dell'Orto's that I picked up a while back.

BP6HS is all you will need - the 7's are a big jump, and unless you'll be thrashing it continuously they will be too cold.

I don't plan on thrashing for a while, but once she's ready, I do plan on driving her properly, possibly including some SCCA runnings. I'll hold off on the 7's until I think she's ready for some pushing and I've got some of these other fuel issues sorted out.

Thanks for the input.
