As I suggested a search here on RCU, from the Walbro thread here on RCU, "These are the rest of the WT Walbro carbs with accelorator pumps.

6.5 mm with fuel pump return spring (4 stroke) WT 366-1 WT 456-1

7.95mm WT 37-1 WT 424-1

9.53mm WT 35-1 WT 38-1 WT 204-1 WT 357-1 WT 367-1 WT 381-1 WT 385-1 WT 417-1 WT 449-1 WT 450-1

11.11 mm WT 29-1 WT 356-1 WT 358-1 WT 464-1 WT 516-1 WT 517-1 WT 527-1 WT 613-1 "



As Yogi Berra once said " You could look it up"

You can look up the parts exploded view on the above carbs to see if they have chokes or whatever else you think you need.

Over and out.
