Ok, next thing is are you having problems with the fuel in the carburetor evaporating? Can you try a bit of fuel down the carb inlet and see if it starts. Underbonnet heat can be a problem but normally the fuel takes time to evaporate, not like when you part up to put fuel in. If you have a mechanical fuel pump, sometime is can struggle to refill the carb and it takes a lot of cranking. An electric fuel pump normally fixes this issue.
One other thing, did your welcome pack get to you OK?
