Function of the dashpot is explained here. http://64.78.42.182/sweethaven/MechTech/Automotive01/default.asp?unNum=3&lesNum=2&modNum=10 As a somewhat related topic, I replaced the choke pull-off mechanism on the Iron Duke (80 Spirit) this weekend. NAPA wanted $33 for the part, but I found one on a Chevy Citation in a local junkyard for $6. The cold start on the car is worlds better now.
