i just bought a 1975 620 and it needs a new carb. i have an old dual 40mm weber carb and was just wondering if that would fit and work. if not what kind of carb should i get? n e info would help alot thanx

Hi!

Welcome ..... your 40 will work if you have the right manifold.

thanx. what kinda manifold do i need 2 get? can i get an adapter plate? would it b cheeper if i just got a 32/36 weber?

You might be better off to check for an inexpensive Weber 32/36 but you will still need an adapter for your stock intake.

Look for both....compare the price if a single side draft intake with the price of a used Weber and adapter plate.

If you go with the Weber 32/36 then I recommend a high rise adapter. Google it and you will see what I am talking about.
