First time using this forum. Owned a Kawasaki dirt bike once, had no issues. But I picked up this 4 wheeler at an auction. They stated it ran, but only needed a battery. Well I do not believe that was all true.
Some pictures are attached. Not sure why, but the whole air filter stuff was removed. They had some small thing inserted as a make shift air filter.
I purchased a battery to try this all out. Waiting to return it and get the proper size, as it was too big for the battery box. But here is my issue I had while the battery was connected.
1 - The lights on the steering column did not come on. Not sure if they work or not.
2 - The starter solenoid seems to be bad. I have a new one on order.
3 - In the pick, there is another rusted part. Not sure what that part is or what it is used for.
4 - What is the 12v rectifier? square bodied part.
So when I hooked the battery up. Pushing the start button did nothing. Pulling the cord to try and pull start, it turned, but would never fire. I have put in a new spark plug as well, it looked worn out. With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.
I have read a few other threads and it stated something about needed the neutral light on. SOmething about a kill switch.
Any help would be appreciated.

I have had a 2002 Suzuki King Quad 500 for almost a year. This is a question I’ve posted before, but likely missed the answer due to being new to the site. Here’s the issue. When in 4 wheel drive, especially in low range, especially when pulling a load downhill, I hear a lot of clanking in the front end. As if the front drive shaft was binding then unbinding. A friend who had a 1987 Dodge 4x4, told me all the noise his front end made when in 4 wheel drive was entirely normal. So, is this something I should worry about? I have all the bodywork and tank off right now doing a valve adjustment and carb rebuild. If I gotta do something, I’d like to do it now. Lastly, I’d love to find a carb tuning guide for this era of Mikuni. Haven’t tracked one down yet. Any thoughts of where to find one? Great forum. Have really enjoyed it so far.

I have a 1991 Suzuki King Quad 300.
I bought it not long ago, and it has never run right. I bought a new diaphragm for it. It's sealed in that department.
It barely ran good before, and actually I got it to run fairly good, with a good pull with a clamp in air cleaner.
I put a snorkel on it, making sure to use pipe that would allow an ID as big as the carb intake flange, so there's no restrictions, and the same clamp on air cleaner.
I went through the carb again, even put a top quality Japanese rebuild kit in it.
It starts and idles perfectly. Has good power from idle to about 1/3, then anything past 1/3 throttle, or thereabouts, it just bogs down and completely dies. If I pull the choke in, I can get it to half throttle without it bogging down or dying.
It pops and backfires and sputters the whole time, then past a certain point the engine acts like I hit the kill switch.
It IS getting gas in the carb by the way, I put on a electronic fuel pump which helped things immensely. I put on a fuel pressure regulator and got the fuel to around 2 PSI.
I am at about 5,500 feet elevation, and the main jet is a 120.
I am considering coring out the main jet to a larger size to see if that helps anything. This quad is already such a gas hog, but maybe if it is jetted right it won't be so had?
Edit: It does actually run a tad better when it is warmed up.
I don't have any lack of power on short hills, but when I get a long uphill road the ATV will slow way down to about 30KPH. If I work the throttle to give it more gas it just gets worse. Then if I let up on the throttle it runs better, but of course slows down even more. Am I looking at a carb problem, or what? I tried getting at the air screw, but can barely get a screwdriver in it and then can't adjust...won't turn at all. I cannot find a fuel adjustment screw anywhere I can see on the carb, and the manual does not show one. My plug is burning black, wouldn't that be too much fuel, and how do I correct that? It may be that the engine is flooding when I go uphill and throttle up.
