I have a 2002 King Quad 300 that has been a fantastic product until now. Starts well, idles well, upon acceleration, begins to run rough and won't to very high in RPM. I assumed fuel starvation or bad plug as the issue. New plug - no change. Have checked petcock valve which seems ok. Also checked pump, and thought that might be the issue. Called around looking for the replacement pump part, and local store suggested they were pretty reliable, and doubted that was the issue. Suggested a carb cleaning. Took the easy way out, and opened up the top of the carb, removed the diaphragm, and put some Seafoam in...and let it sit for an hour. Upon turning over, it wouldn't fire at all. After a couple of tries, seemed to get a hydraulic lock. So, pulled plug and turned over, spitting out a lot of fluid. Re-installed plug, same response. Now, getting gas leakage on to floor but haven't been able to trace it down exactly (suspect from carb but not from top where I re-installed the diaphragm). Any ideas? Thanks.
I have a 96 Yamaha Big Bear 350 2x4 which up till yesterday was running ok. However out of the blue as I was going through the field it started missing if you tried to go over half throttle. It will start and run up to about half throttle and then it starts to miss. I changed to a new spark plug thinking it maybe had some carbon buildup but that didn't help. I put a new filter on it this spring as I do each spring but it seems more like something electrical in nature. Anny ideas? Thanks
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
