Those are my current issues. I have been working on this for weeks. Here's a list of repairs I've done.
1 Replace spark Plug with NGK.
2 Cleaned/rebuilt carb
3 Replaced CDI
4 Cleaned/rebuilt carb
5 Replaced coil
6 Cleaned/rebuilt carb
The reason I have cleaned the carb so many times is I keep telling myself it has to be a fuel issue and doubting the my clean, because when the UTV stalls, I will pull the plug and check spark. It has spark! I went very in depth on my last cleaning. I have full faith the carb is cleaned and A/F valve is very close to where it needs to be.
I'm stumped. The spark plug definately does not show the motor to be running rich, possibly a little lean. Just to test how long the UTV would run, I set the idle screw to about 3000. The UTV ran for 2-3 mins, then fell on its face.
I haven't touched the stator or pickup coil.
Any and all help is very appreciated!!
