Mikuni mileage? 140-160 1972

I'm wondering what other people are getting for mileage.
I have a fresh engine with twin HSR42s that gets 17mpg at about 3000 miles break-in while my 68-142 (freshengine too) gets 27mpg with a Weber32/36 carb.

Rear HSR carb has tendency to leak at idle. Cleaned float bowl twice and there are 2 fuel filters before and after fuel pump
