I am new to this forum and hope that someone out there can help me, I have an early Suzuki King Quad 300 (280cc) which starts intstantly every time but at about half revs or there abouts it starts spluttering and will not rev any higher, this fault is present whether choke is applied or not, some one suggested that silencer maybe be clogged so removed baffle but no improvement have removed carb and stripped 3 times but still no joy.
Any ideas would be most welcome.
I don't have a ton of electrical experience, but I think the basic workings of a regulator/rectifier are pretty straight forward. 3 diodes, so 2 power wires and 3 diode wires. Symptom is relays click on/off, more or less no power, sometimes will work, mostly no electric to switch, can jump solenoid and it runs.
If i understand a reg/rect correctly, i should have constant resistance one way on each power wire. So in a total of 12 ohm tests (3 per power wire, one way positive, one neg so 6 for one wire, 6 for the other), i should have 3 resistances one way on each power wire, am I correct? And they should all be reasonably close in resistance?
If i understand the way the reg/rect works correctly, then I have one bad diode as it doesn't read the same as the other 2 and this would be the cause of my issue?
All testing performed on the reg/rect unplugged on workbench, with a Fluke.
Just picked an '03 Bayou 300 2WD. It runs ok, needs a little help though. Maybe someone can answer some questions for me.
1. The choke "off" position is the lever all the way right, correct?
2. The choke seems mechanically... funky. It has a little valve clamp around the rubber boot where it goes into the carb, seems kind of janky, I don't think there's typically a valve clamp on that part? The engine seems like its running really rich, smoking a bit, so I wonder if I can just completely remove the choke cable to see if that's part of the issue? But I don't fully understand the choke needle setup. Is "choked" when the needle is being pushed in, or pulled out? Like it I chopped the cable just outside the rubber boot by the carb, would I be permanently choking it or permanently unchoking it.
3. I've read that I can tweak the air/fuel screw and maybe fix the rich mix. Where is that even located, and if it's behind a cap that I have to drill out... where is that?
Thanks for any tips
