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
I have an 04 ltz and it started sputtering a little bit while going down the road and I was low on gas so I just figured that's what it was. But now I can't get it to start I completely cleaned the carberator put a new spark plug and coil pack in it and all it does is turn over. It has compression it's getting fuel and it is sparking but all it does is turn over any idea what it is??
I'm new to this forum and I hope you can help me out. My '99 Polaris 250 Trail boss does this: shifting in to forward the gears grind a bit. Once in gear the rig wants to immediately move forward. If I don't get to the throttle fast enough, she stalls.If I do, off we go. It happens everytime I shift into gear.Could this be caused by dirt inside the clutch sheaves causing the belt to engage early (before any throttle input)? Or what??? Thanks in advance.
