It was built by a gifted technician in Toronto and raced by a friend for
four seasons prior to my acquisition of it. I've never seen a box-stock
Gold Star in my life. How in hell would I know anything about stock carbs?

By being born sooner grin. It was a GP pattern Amal.

My Spitfire and 441 Victor, and the Triumph all had stock carbs, but I have
absolutely no recollection of what carbs they had. ...

If the Spit was a '66 it too had GP pattern Amals. After that the Spit was a
Lightning with the small tank and used regular "street" Amals which had idle
circuits and integral float bowls. IIRC the Vic did too.
