PX200E jetting problem with OKO PWK 28

Hello guys.  I am a new comer of 2 stroke engine and Vespa.

I do have a 96' PX200E given by my friend.  And I decided to renew the shell myself.

I found that the stock 24mm carb have some oil leak problem so I decided to buy a OKO 28 carb instead.

I've read some jetting articles from the web the average of those setup (200cc engine/ 28mm carb) is about 130 for main and 42 for slow.  I try to follow the setup but found that setup but some excess fuel pour out from the carb.  What is the recommend setup for a normal engine?

And I am using the SIP Speedo 2.0.  What is the temperature range of the cylinder head temperature?
