201 not starting hot

[Westphalian]

Hi, I bought a used MS201 CM a few years back for limbing. it no longer starts when hot. Because the starter rope pulls fairly easily I checked compression which was 1500, the cylinder had slight scoring but I am no expert. I took the opportunity of giving it a deep clean and retuned the carb and at home I thought I had sorted it but obviously on site after one tree it wouldn't restart. After a google, people are saying fuel filter, spark plug, vapour lock or ignition module. Can any wise person put the possibilities in order of likelihood so I don't waste too much time and money?
Thanks

I had the same experience and the issue turned out to be that the wiring to the switch were damaged.
