Got a 92 fortrax 300. Won’t run past half throttle idles ok but not good. Backfires and black smoke at wot
What I have checked. Oil and neutral light work. Tried new coil and plug. Carb kit but was spotless when i took it apart. New cdi. Stator ohm good charging 13.7vdc running. New battery, pulse coil didn’t pass ohm test replaced it. Checked valves were tight but the timing chain is toast but didn’t jump time. Compression is 150 psi cold. It has a decent spark when cranking it over but I’m lost I cannot get it figured out!
