AF suggested the following for my rapido with a 30mm Amal non power jet , would have thought the 34 won't be too different

30 - 35 pilot
50 - 55 choke
107 needle jet
320 - 340 main
3 1/2 slide

For a ts1 with expansion their chart says the same but 340 - 360 main.

If you're using the power jet you subtract the value of the pj from the main.

As to the hole you'll need to see if the panel fits ...if there's clearance then you ought to be ok , I think that you need the bel mouth on for the power jet to work...
