72 350sl funny idle where to start


well the 72 is now running starts right up and all systems go. but... it has a funny idle. when first started the rpm goes up then rapidly down up down up down and so on. after a drive it seems to stop.

now it did this the very first day we bought it. we drove it and it seem to stop didn't any problems on a 1500 mile drive. so this issue is not from it sitting for 2 years.

any body got any ideas?

it also seems to run extremely rich now. alot of black smoke comes from the pipes on start up. makes me think something in the choke is not right.

tks for any help
Thanks Much!
