2011 txt 300 starting when hot

[Glenn]

Just bought a 2011 txt 300 with less than 20 hours of use and it starts fine cold, but not when it's hot.

I can bump start it and it runs fine.

I have read some posts suggesting a spacer on the head and bigger jets.

I have not changed the plug or anything yet. I'd like to start with the easy fixes first...

Thanks!
