Good Day All

The '71 Bee has been in long storage. Got it out a couple of week ago, dusted it off, changed the oil and fuel filter, checked everything, went for a cruise. Everything worked like it should (except for the cruise control). Roasted the tired a couple of times filled the gas (93 octane). Had an exhaust leak which ended up being the choke thermostat pocket gasket. Unfortunately, when troubleshooting this, I ended up removing the intake. That ended up with the carb coming off to replace the base gasket. Since then I've got it out when weather permits and all was well.

Today, I took it of to my alignment guy. On the way home it stalled in traffic. Restarted okay, but the acceleration is not smooth. Once out of town the hammer dropped. When the speedo reached 50, the motor started to surge like you were stepping on the gas, then removing your foot, and stepping on it again. It did not stall.

Once home I checked the timing, fiddled with the carb as per the shop manual, all to to avail. The car starts fine, drops to curb idle when you tap the gas. When you take it out there is a 'dead-spot' when you accelerate (approx at 1/3 throttle). and it will start to surge when you reach 50 mph.

The Bee is a 383 automatic with a Carter AVS.

Any thoughts?
