I am currently fighting with carb as it has original Amal Mk2 and start that pig is like half an hour afair so I decided to either buy Mikuni VM34 or give another chance to Amal going down with main jet from 210 to 180 and mounting some air filter as currently there is none.
Looks like your forum is the best place all over the internet to get some information about how to set up these engines properly

I live in New Zealand so everything is even more difficult as I have to order carb parts from US/UK and it takes ages to get them.
