  2. Thanks everyone, found out it's a 1998 Yamaha Timberwolf YFB250
  3. Hi everyone, I received a 98 Yamaha Timberwolf from my brother for free, and I'm working on getting it going. I am having the following problem: The engine is backfiring through the carb. I have done the following to try and get the four wheeler running: Rebuilt the carb and set the air screw to 1-1/4 turn out and the circlip at middle position 3 Replaced the coil, because the cable was loose at the coil end Repaired the main ground, coming from the battery Replaced the ignition switch, because my brother couldn't find the key. New switch tested good Tested the kill switch and it tested good New coil tested goodfor both primary and secondary coils Pickup coil resistance is at 195, which is correct My source coil, is where I believe the issue is. The resistance is 310ohms, and it should be between 428-523ohms When I opened the stator housing, there was significant oil, which I have read is normal. Does it sound like I'm on the right track replacing the source coil? Could this be causing my backfiring issue? It looks like the source coil is part of the stator assembly, is this correct? 4BD-85510-20-00 STATOR ASSY
  4. I just received this from my brother, and neither of us know anything about it. Can anyone help? What I do know: 4x2 1500cm marked on engine pull-start difficult to push with flat spot tires lol
