It's got the deceleration pop, (more like a BANG!) and the exhaust flange gasket is pretty much gone, but the pop back through the carb was late timing. It's running a lot better now with a few degrees more advanced dialed in, and the exhaust note has changed from a roar to a purr. Gas mileage still sucks, though! LOL!
