Help with carb setup

I have a carb on my CT125 bucket that is smaller than the port. See diagram. I'm thinking either a spacer with tapered throat as shown - or should I get a bigger carb. The bike seems to starve for gas at the mo

I've got a pair of CB250T carbs if you need one.

I'd probably keep the carb

and get rid of the CT.

Would it fit without major mods?

Cheeky. She's a rocket when well fed.

Just measured them. Intake 32mm inside dia, 38mm outside dia, so I guess it's a bit big. A custom manifold adapter would have to be made as the starard ones mount holes are 68mm between centres.

OK - I think that I need to look at 25-29mm size to avoid the problem of too little vacuum. Thanks anyway. Anyone else with knowledge or suggestions?
