00 suzuki king quad 300 burnt regulator/rectifier connector

As stated above working on a 1999 Suzuki LT-F160. I think I’m having trouble with the carburetor. I keep fouling spark plugs. Full disclosure, I did make a poor attempt to “rebuild” the carb (that’s why I think that’s the issue). No idea if the new parts are at the correct “settings” (gaps and such) I believe the starting point is 1.5 turns from bottom out on the adjustment screw (is there another adjustment I don’t know of?).  Doesn’t feel like I’m getting gas drawn through the carb (clogged jet maybe?), the plug isn’t wet at all (assuming why they’re fouling?) Not a great deal of experience working on carbs and not having much luck on finding a lot of info on the 160’s.
1st- by chance can I swap out the original carb (13200-02C03) for an LT 250 model (think the HA01050). They’re only about $30 apposed to $200. That would at least narrow down if it’s a wiring problem or carb issue.
2nd - The wiring has been minipulated at least a dozen times (before I acquired it, my cousin got it from a buddy kind of thing). Hopefully don’t have to dig into this too much as it’s currently a bit if a mess. 
I was told it ran last year... 
Any imput would be greatly appreciated

Hello everyone, i have 2000 Polaris Trail Blazer 300 I’ve been stumped on for weeks. I’m having a lot of issues starting the quad. I cleaned the carb spotless because I thought it was a carb issue and bought a new fuel line because it wasn’t getting fuel. The carb gets fuel perfectly fine now but it won’t start. The spark plug I a little worn out but it’s good enough for just one start. The only time it does “start” is when I spray starter fluid into the carb. But it never stays on. It’ll start for a bout a second then just die out immediately even if you’re giving it some throttle and the choke is on. I have no clue what I should do. If you need more information, have questions, or have any slight idea what the issue would be and how I could resolve it. Please reply ASAP. Thank you.

OK ya'll.My son bought this thing and was told its a Kaw Bayou 300. Maybe. I cant find any numbers on it.The one tag I did find its so faded as to be unreadable. Its a long shot but maybe someone can help ID it. Thanks in advance.

Pretty good video on the history of Suzuki ATVs if you are interested in some ATV education. Starts off from when three wheelers were the norm.
Suzuki, A company with about 100 years of manufacturing history is company built on bold innovation and the courage to push forward with new ideas. One of these new ideas was created in 1983, when Suzuki invented the first four wheeled ATV and introduced it to the world. At the time three-wheeled ATVs were the norm, and Suzuki’s four-wheeled ATV the LT-125 created an al-new vehicle category and literally changed the industry.
 
 

I have a 2000 Arctic Cat 300 4 wheeler. I have been having some carburetor issues. So i bought a new carb. Now I'm having these issues. The unit will start and idle fine, when i go to accelerate it wants to cut off. So i checked to make sure it was getting gas and the fuel filter will be full of gas and then once the carb opens the filter drains down and will not refill quick enough to run. So i checked to make sure gas was flowing to the filter and it is flowing fine through the line. I remove the filter and run the gas line directly to the carb and the engine idle fine and then it will run good as i ride it for about 10 minutes then it will start with the same issues again i cannot accelerate enough to move the 4 wheeler. Every time i accelerate the unit will cut off. What is wrong with this thing. My 400 Arctic Cat is doing the same thing except it will backfire, I'm lost i have tried everything i know to do, what am i missing here. Thanks for your help
