I have an old school 650 DP Manual Choke. If that will do. Asking $250. It is in totally rebuildable shape. It has been sitting a while on my shelf inside. I swapped it out for a 750 DP about 7-8 years ago. Swapped between them a few times, hasn't run in maybe 4 years. It has check balls for Acc Pump One Way Valves. I believe it is from the 70's.
I also have a set of jets if I can find them. The big white box with like 25 different sets. $30
