Hello Im new in this forum.I ask your opinion on the restoration of Vespa Sprint, 1966

Hello I am from Portugal 41 years and I like Vespas

 
I ask your technical opinion.
 
I am restoring a 1966 Vespa 150 Sprint I used the original parts.
When I bought the bike was locked for being long stop using oil and patience it free the piston.
I have had some difficulty in fine tuning the carburetor, I think that is spent in high failure and dies.
Can be a problem in the cilinder?
Or is it just tuneless carburetor?
Wanted to know what your advice as to replace the carburetor and the need to replace the cilinder kits which I recommended, 150 cm3 or 177cm3.
Call for prices:
- Carburettor
- Drum kits, for those that I recommend.
 
I hope I have explained properly what I want.
 
I look forward to your reply.
 
Compliments
