What Dodgeman says has a fair bit of merit. The only issue that disagree with (and not too much) is his comments about carb. size.
Provided that the oversize is not way over the top, it is always possible to tune an oversized carb set up. For example, I was using an A14 Sunny Wagon with a 32/36 Weber that had been dyno tuned as the delivery vehicle in our business and it was terrific. There were no flat spots--- the engine opened up cleanly and just pulled its guts out. The worst fuel consumption around the 'burbs was never less than 30mpg and about 36 on a run. The car was never driven less than moderately hard, because A14's like to rev. and they rev better with the bigger carb.
On the other hand, an under carbed engine can never be tuned to any degree of satisfaction.
The moral of all this----If in doubt, think bigger rather than smaller, keeping in mind what you want to achieve

To 89mm
Thanks for the comments, & the fact that your A14 Sunny was dyno tuned agrees with what i have said. The Webbers real advantage lies in it's tuneability, but few manage to do it right, & a dyno is the only real way to get it right.

You also mention the fact that it had a Webber. The important part of that sentence is the word "a", which i have taken to mean "one" This too agrees with what i wrote.
Finally you write that it was a 32/36. This means to me that the smallest size of the venturi is 32mm in diameter which also agrees with what i have said.

It sounds to me like you got it absolutely right. Right carb, right number of them, right tuning method,....right on! The fact that you are completely happy with it makes me feel all warm & fuzzy inside.

A carb that is less than the "optimum" size can still be tuned to run real good, but it's best performance will be lower down in the rev range, although something like a lawnmower carb might be going a bit too far.
