40 Dellorto Jetting for 1916 pobjoy


Question asked on ebehalf of a mate of mine,
He bought a 1916 pobjoy with cadrons and recently managed to score a new set of dellortos (from someone at the an alfa club).
So having purchased all manifolds and linkage we are about to give them a go. What jets /chokes /emulsion tubes etc are people running with these dells carbs in similar engines.

Note its not the "steroid" cam engine.

Most Dells come with 9164.2 emulsions
Mains 4.2 x vent size
I have 34's is a stockish 1916 - so 145 mains
Started with 60 idles and it was popping a bit
Went to 65s and all is fine
