I also think your new settings look good. This what I've been using on the new Dellorto carb kits with for a 2 liter engine that we sell in the Club Store:

Choke .............................. 34 mm
Main Jet .......................... 145
Main Air Corrector Jet ... 190
Main Emulsion Tube ...... 7772.8
Idle Jet ............................. 55
Float Needle Valve ......... 170
Pump Jet .......................... 45
Starter Jet ......................... 60

Note: 34mm are used instead of 33mm and the main emulsion tube is now 7772.8 as 33mm and 7772.5 are no longer available as new parts, these make virtually no difference in the overall settings however.

I have to say, an overnight soaking in carb cleaner may not be enough to clean out an old, ex-UK set of Dellortos. These things can get pretty terrible over time and the varnish built up can be work to remove. The carb cleaners and soaking agents they sell at the auto parts stores these days are nothing compared to the deadly, yet highly effective cleaners from years ago.

As much trouble as a Dellorto conversion can be, it is a great upgrade, especially with a performance/2.2 engine. Your patience will rewarded later on down the road.
