Its probably the original pull off..when I bought the car the PO told me the carb "probably" would need rebuilt because it took forever to start...found that the choke was bad. Replaced the choke and it starts right up now but after a moment or two it starts to load up.....found a bad pull off. Car runs fine on the road, doesn't stall, doesn't surge and idles well. With replacing the pull off I will also eliminate a vaccum leak.....:tongue5:
