Hi everyone,

I am a new member. I am Belgian but I live in Argentina. I have a Cat 250 2x4 - 1999 and a foreman 450 - 2000. I do some nice trail riding here in the mountains. I have been reading the forum for a while and it's very interesting.
I have had some problems with my cat. Spark plug is getting black even with new plug. It get a little better when I take the air filter out but not much. I have cleaned the carb and changed the needle to position 2 starting from top. I don't know what is the exact mesurement for the float. If anybody could help me trying to solve this or have a manual it would be great.

Thanks

Franck

 

What elevation are you riding at?

 

Try adjusting the pilot jet screw.

 

I m riding between 2000 and 6000 feets.

 

I have been trying to adjust the pilot screw with 2 1/3 turn
