Answer
Dear Martin,

It sounds to me you should check the following:
Is the fuel reaching the carb okay.  Is the line kinked or detached or etc...
Remove the spark & check the gap is correctly set. Clean electrode use a fine file to square the edges so that their sharp.
Is the plug fouled? Does it need replacement?
If you need to do an overhaul of the carb, [as long as the adjustments are fine] I would take the carb off the engine. Clean the bowl. Careful using too harsh chemicals since they can damage rubber seals/gaskets around the carb.
Also Check the choke & throttle controls to ensure they are not allowing the valves to move during operation. Check the crankcase reed valve , beside the carb, see if it is stuck or clogged.
If the crankcase is not airtight the engine may lack power.
Lastly, if the piston rings are worn or the cylinder damaged the power can be reduced.

Hope this information is helpful.
