Dellorto Phbn/phva question

Kinda almost sorta out of the moped realm with this Rieju RS1.

It's got a 12mm phbn and it keeps leaking out of the overflow. Yes I've cleaned it, the float height is good, needles look good but I feel as if my float needle is worn despite it's appearance. Maybe I'm missing something about this carb?

Anyway, browsing the webby web for a rebuild kit I keep finding some parts having both phbn and phva in their compatibility descriptions but can't find anything saying what specifically is interchangeable, or if I'm reading it incorrectly.

I only want a float needle, but they seem hard to come by and everything I've viewed needs to be shipped internationally from the UK.

Can I use the phva float needle? Or do I have to keep it phbn? Phva stuff seems easier to come by. Any input is appreciated, I have little experience with both of these carbs

Thanks peeps

It’s the same needle. Order the phbg needle and run it.

Re: Dellorto Phbn/phva question

After posting this, I find the answer.

There is one difference between a Phbn and a phva, the starting choke mechanism.

Thanks for the input Todd!
