As I said in the beginning I am using fresh fuel - I have just had the tank out and fully cleaned and treated and replaced the fuel line as well. I am also using a new set of plugs. I read a very good article today on Zenith carbs and it explained how they actually work. Under starting from cold it said the strangler would be fully closed AND THE STRANGLER VALVE! I didn't know there was one but when I looked at the "strangler" or choke, it was fully closed BUT the valve was stuck open. When I dismantled the choke the valve broke off so I am now awaiting a new one. I would like to think that this is the problem but will wait and see. There seems to be doubt as to whether there should be a strangler valve on my carb but it does show one in the drawings for that carb
