Thanks for the historic lesson John.
Your broad knowledge knocks me out of my socks every time I read your posts.
With anny respect, but all that don`t aswers my question how it is possible that we got many way overcarburated (at least on the paper) engines arround that run great and get good milage.
When I understand it right the different methods of messuring cfm result in variances up to 20%.
But we are talking about more than 200% (again on paper) with a side drought Weber setup for example.
And than there are carbs that seem to cover almost everything.
The 525 Road Demon -for example - is advertised for engines from 260 to 400 cid.
How can it cover this wide range? Is it the vacuum secondarys or bigtime rejeting?
I also heard that a Q-jet can be thrown on almost eny engine and performs great.
