Some jetting advice if poss.

I’m running a Honda 205 stage 5 with a 44mm clubman
I was running a 30mm mk2 Amal open mouth with:
Main jet 210
Pilot jet 40
Choke jet 50
Atomiser 107
Needle 2D1 second down
No.4 slide
3/4 of a turn out on airscrew

I am replacing the carb with a 28mm Dellorto phbh with a remote breath sweet filter and am looking for jetting suggestions. Thanks in advance 👍

AV266, X7 Needle, 118 MJ, 55 pilot, 60 choke, 300 float valve/needle - this will be a bit rich
you may need to drop to a AV 264
