Hello. Just wondering if anyone's got an idea what the problem I'm having could be. I've got a 6v71 blower, fully rebuilt, sealed etc... The blower's securely mounted with all gaskets to a blower intake, all properly installed. When attempting to start the car, it runs at about 1100 rpm for a few seconds after cranking, then dies. I believed this to be a vacuum leak at the carbs at first, but I'm not entirely sure, just looking to see if anyone could help.
