I think this is the IDF version. I used it with DCNF carbs. You may have to adapt it for your use.
The optional return spring is not included. It is available on CIP1 and maybe elsewhere. There are two versions. The one for the steel base should be used. It may be that any springs on your carbs are sufficient. For a while, I connected a spring from the upper cable arm to the deck lid latch cable tube.
The sale price on CIP1 is $140 right now.
My price is $65 plus $15 for shipping.
