Sounds like it's flooding with fuel. Does it also barf some black smoke out the exhaust?

more likely a weak spark, possibly caused by oil in the disty.

cleaned the dizzy have not changed the plugs yet waiting for them to arrive would a dirty dizzy and shit plugs make it smell it sometimes stinks of fuel when i put my foot down?

possibly, the theory is that the fuel drowns the spark, so you will get a load of unburnt fuel. Usually the symptom is stalling when trying to take off and apply power, or just generally applying power.

check the float in the carb, it's probably leaking and filling itself with fuel
