You don't mention checking that the carburettor piston in the dashpot can be lifted all the way and will fall under its own weight when released, making a distinct click when it stops. If the piston does not rise and fall freely you will have problems. Also if the carb is HS type it must have oil in the damper, if stuck engine oil wwill suffice. Carburettor and ignition faults frequently get confused because they can show similar symptoms.
