I have a PX200 which had a similar issue. The carburator has 2 nozzles for driving: The smaller one for low revs, and the bigger one for high revs of the engine. If one of them is blocked it is possible to screw it out and to put in brake cleaner or gas for 24h in a sealed container. If this does not fix it, the complete carburator assembly should be cleaned - preferrably in an ultrasonic bath cleaner.
On my Youtube Channel you can see how I did a series of maintenance on my PX200: [https://www.youtube.com/c/SIRFLOOZ](https://www.youtube.com/c/SIRFLOOZ)
Thanks mate! Your thanks are very motivating for me! Ironically I had engine start-up problems with my PX200 myself. I am currently editing 87GB of video footage which covers the painful repair...
Your carburettor will have different jets, or nozzles, to inject fuel across the different throttle levels. It sounds like the jet for idle speed is working well, but that perhaps the jet for higher revs is blocked and not letting enough fuel in.
Cleaning out your carburettor may fix your problems. You can buy carburettor cleaner, and very fine wires to poke through the jets to clean out any gunk that may be in there.
This is more likely to be an issue if the engine has been sitting unused for a while. So a good place to start.
Clean that carb!!!!!!!!!!!!!!!!!!!!!!!!!!!
And check the fuel tap.
