How do I know if my dashpot is working properly. I installed a rebuilt Autolite. Drove my 68 from Pa to SC...no problems except one episode of sputtering but I was low on gas so I figured that was it. Filled it up, drove back to Pa and now the problem has returned with a vengeance. Looking at other threads led me to the dashpot. It plunger (which I assume is suppose to spring back into place remains in the same position. What are the specs for setting it and how can I tell if it is working properly?
