After driving only 36 miles my new Holley 650 has started to leak. It has a drip from the right side from the bottom of the vacuum secondary rod. The truck has had problems of "running on" or not dieing after the switch is placed to the off position, which caused a couple of backfires. Is it possible that the diaphragm has suffered from this? Thanks in advance for any help.
P.S. I'm asking BEFORE I tear into this so at least I'll have some Idea of where to start, it's a PITA to get to now that I've got the truck built....
