The first two numbers are the types of carbs the vents fit- 32 and 34 PDSIT. The last number is vent size- 24. |
This helps a lot. I wonder how many sizes/combinations are available. I guess venturies from the Type 2 carbs will fit the Type 3 carbs?.... Thank you Tram. |
Yes, they do swap, as some guys are using 28mm or larger venturies in their larger type 3 engines. They're also jetting up as well. The problem however is the stock air cleaner assembly is becoming a limiter on engine size.

That is exactly what I was thinking. I have a 1776 bilt on a Type 3 case with a 110 cam with very small ported and polished heads that I can put on the stand and tune there before installing. Even though the engine on my Fastback since to run good,,,, I think more tinkering could be done with the cards. But I am living it along untill I have a spare ready to go. I want to be ready for cruising season. It will be here before you know.
