Hi,
The engine and cyl head have a code of C5DE which I believe are 65,
It is an automatic C4, I am going to advance auto today, the have a reman distributor for a 65/67 single diaphram, the distributor that came with the basket was a dual diaphram, there is no smog equipment whatsoever, I am guessing the carb is probably a 67, when I rebuilt the carb after cleaning I took a can of carb and choke cleaner and sprayed through all passages they seemed to be open then blew compressed air through them, I noticed that the carb has a hot water plate under it, I am going to put a valve in it to stop the flow in warm weather I realize in cool and cold weather it needs to be open to keep the venturi from icing, but I feel with the warm weather we have it is causing the carb to boil when shut down hot, what do you think of pretonix ign system? this has sure been a learning experience, lots of new cuss words learned, I think the guy I bought this from just cleaned out his garage and I was dumb enough to buy it, but... when all is said and done it was worth it.
