I am new to this list and have recently purchased a 68 Crown that had quite a bit of work done on it by a previous owner and is in very good condition overall. The carb on the engine was rebuilt, and it has pertronix electronic ignition. The problem I encounter is that when the engine is cold, I have to pump the accelerator 10 times or more to get the engine to start. When the engine is warm, one pump or holding the accelerator down partway does the trick. I am wondering if this could be a problem with the automatic choke or???? Any suggestions are appreciated - thanks!
