I have posted a picture of my NOS fitting kit in the past:

Nick, what type of cleaner did you use on the on the carbs ?? The cast aluminum is very clean and bright.
I have used carb cleaner in a 2 gallon pail from the auto parts store.
Thanks
Jim

I found Mark had a clearer scan of the H4 sets in AKD3509, starting at page 450

Another quick question for the experts - did any of the special tuning sets have the "fast idle" parts like these? I can't see them in any of the parts catalogues for the mini setups. I assume on a racing mini you'd just hold the throttle down till it warms up

And sorry for all the questions, apparently "H4" is an unsearchable term on the forum so a bit tricky to find old info

The fast idle parts weren’t on the ST setup

I found this to be a very interesting thread and topic. I have what appears to be now a set of the works H4 carbs. A few observations are that it has the 661 manifold the 4814 and 4815 float bowls. The fast idle cam parts were not on the carb and the carb body does not even have the boss and tapped hole for the pivot pin for the fast idle cam. I always found this strange. It does have the choke lever lifting wires that attach to the choke cable.
Just a few bits of info to further identification what carbs you have.
