i have a 98 trailboss 250 2 stroke and when it first starts, it idles fine then after i drive it for about 10 minutes or when it starts to get hot, it will only idle for about 10 seconds than it will idle down lower and lower and finally it will die. do i need to turn up the idle or is this a air flow problem?
thanks for any help

 

it is also dosent like to start when its hot. does anybody know what might be causing this any help would be greatly appreiciated.

 

Sounds like a rich fuel problem, especially the "after it warms up" part - possibly even the choke valve is not set correctly, allowing the choke valve to be a little bit open all the time.

 

What can i do to check these things, and what do you mean by a rich fuel problem.

Thanks for the reply.

 

make sure the float is set right and not sticking.

 

Turn the air fuel screw out a half a turn, if it gets worse go in a half.
