Happened to me recently...Running great, then, nothing. MY problem turned out to be a sheared flywheel key. Check your timing.

If he changed the trigger,then the key was put back in,so it shouldn't be a problem.
First do a compression test.
Then start with the fuel.
Unhook at the pump and squeezie some into a glass jar.
Check for water/crud in the gas.
Then check the fuel pump.
Clean the carb.
Float level?
Do this and get back.
