A vacuum leak on an ede carb is usually not an internal issue. It's a sealing issue between the baseplate and intake. IMO, taking it to a shop is just burning money at this point. You really need to do the simple stuff first, like locating the actual source of the leak, before throwing cash around.
If the intake has an hourglass shape opening like a performer, it's going to need a 2732 (???) plate to seal it up. Carb linkage also hangs up on the intake sometimes causing leaks. Power brakes? Disconnect EVERYTHING vacuum related from the carb and plug it, see if that helps. If it does, then hook each item back up until you find the offender.
No timing tape or marks on the balancer for 15 and 30 degrees BTDC and you'll never know where the mark is unless you have a dialback light. Put the inductive pickup where ONLY the #1 wire is located, up front near the plug. Just don't burn it on exhaust manifold/headers. No need to place it near the cap if that's what you did.
