I have a 1998 magnum 425 runs good till half throttle then backfires/loss of power. I have cleaned the carb twice, good fuel, good compression, cam looks great, bypassed the override, throttle sensor good. when I bought it, it had problems. stator was replaced but not flywheel(missing magnets). replaced flywheel but don't have a tach so I tried to time it painstakingly 1 degree at a time to no avail. besides it wont hit 3500 rpm the way it runs. pulling my hair out HELP. lol

 

No need to post twice in this section and the expert section also. Causes confusion.
