Rick, It’s the same as a Nova Rossi .46, that’s why so many people are looking for any NR or after market carbs for a NR46.

I am aware of that!!!
Would like to know what size the neck is...as I have a K45 in hand and my NovaRossi 21 carbs fit it...
Which doesn't make sense to me.
So my next question is, what is the bore of the NovaRossi 46 carb?

15mm bore on the K-45 housing. I think both Novarossi .21 & .45 are 15mm neck.

I’m using a carb I.D of 11mm

Thank you Buck...
Was quit surprised when my 21 carbs fit the K45.
Will have to look @ bore in the morning...
This is for Coach, new sport-40.

Yes the nova 21&46 have the same neck size.

 

[FloridaScaleBoater]

Yes the nova 21&46 have the same neck size.

Do you have a bore for the 46 D?

Many of the OS 21 sized carbs have the same neck size.

Yes. I don’t know of any .21 motors that don’t use that neck size. There probably is some but all the ones I’ve held are the same.
