I have a 1994 XT 350 too and I have a problem on starting it when it is stopped four about 24 hours. I kick the kick down and it start´s for 3 seconds and then it stops, this happens always during 10 minutes after that it starts and goes well, but this only happens while the engine is cold I think it must be a slight tuning on the carburetor, could you give me the right tuning’s for the carburetor ??? if you can please help me . Thanks in advance.
