i have just got one of these from a deceased estate i have put in new fuel and spark plug, the problem is it will start on choke and run between 5-20 seconds then cut out if you try and open the choke whilst its running it cuts out, and i cant get it to fire at all with the choke half or full open, i have checked the petrol cap and its breathing ok, have took the exhaust off but still does the same can anyone help ?
