Greeves Scottish 197 9E - Carb Query

[ronwright26]

As my Greeves Scottish is an unknown quantity I thought it would be prudent to check out the carburettor that is fitted.
It is a monoblock 376. I have been looking through my library of books as to what the correct main and pilot jet should be and I am getting conflicting advice.
What should the carburettor settings and jets be?

[Colin Sparrow]

It would have started life with a Villiers carburettor, so if originality is important you've got the wrong one. If not, I'll leave it to others to advise on jets etc.

I am not to concerned on originality - much prefer to get the bike up and running. I have just checked the carb now that it is back from being cleaned by ultrasound. The main jet is 105 and the pilot check is 25.
