Kangaroo fuel.

Perhaps a slight exhaust leak in the motor bay. Exhaust getting into the carb air intake. Could try putting a metal dryer vent hose or similar over carb intake, hang it from the hood support rod, route it up to up towards the radiator. I had surging issues/poor idle that drove me nuts. Did this and issue went away. Found a small exhaust leak where the exhaust manifold mates/clamps to the muffler.

No. A low compression engine runs best with no back pressure.
You can tie a tin can over the end of the exhaust fairly tightly to create back pressure, (will run quieter) and try it.

I totally agree with you updraught. The fitted exhaust pipe/muffler is virtually unbaffled which would improve the scavenging effect of the exhaust gasses .
Will try the "tin can" muffler and report back.

Um. Clutch adjustment? A slipping clutch will result in the acceleration symptoms you describe which even out as the car comes to speed (and the torque is diminished.)
