I did some research on that Monojet, it is a well engineered carb. I found this which may help determine the cfm of your Monojet:

According to doug roe's rochester book 1973 printing (@ 3.0in. hg.pressure drop)
1-7/16" throttle bore with 1-7/32" venturi is 160 cfm
1-11/16" throttle bore with 1-5/16" venturi is 210 cfm
1-11/16" throttle bore with 1-1/2" venturi is 250 cfm

Where are the cfm numbers in the link? I looked quite extensively . Tec section, specs, and a couple others

The cfm numbers are from someone name Doug Roe, a Rochester authority.
The link is to carburetor parts article on troubleshooting, rebuilding and associated.
I recently became interested in Rochester carbs and did a bit of investigating online but not well versed by any means.
