Check with Max.

generally a good place to start with 97's is stock jets...

JWL found best jets for 2 Strombergs on the dyno with stock 239 were .046.
Many reccomend smaller. I have a 276 and found you really have to watch for detonation. His book is helpful and discusses jetting in detail.

Are you by the sea or up in the mountains ??

Hmmm...my '41 with a Stromberg came in from Albuquerqe...I am close to the Pacific - should I change the jets?

From looking at the grayish insulators on the plugs, my 284 59A/B with 3 97's with stock .045 jets on progressive linkage runs a little lean, but very well. Great acceleration. No backfiring through the exhaust. Getting 17 mpg on the Interstate. I am usually near sea level and have not run it at elevations above 2000'. So I would say that .045 would be a good starting point.
