My cotton candy machine is not working. When run, machine overheats and doesn't spin webs efficiently or at all. What little is produced is burnt tasting. After 15 mins machine smokes & boils sugar.

Back story: Hello, My name is Jack, and I own a commercial cotton candy machine sold by Carnival King which I bought to help my school club raise money. The model number &/or name of the machine I bought is called the CCM28. When I bought it at first about 4 months ago the machine worked exactly as it was advertised which was perfect for me. I used it for personal use about half a dozen to a dozen times in the two months before my club needed to use it. During each of those times, the machine worked great and allowed me to make as much cotton candy as I wanted for about 45 mins before requiring me to give it a break so the machine can cool down. Then the first night out in public with my club the machine started acting up. For the first 20 minutes, the machine was not working nearly as efficient as it was in my house, about 4 times as slow and twice as much sugar. I figured this was because of the wind and that would be a problem as long as the machine was not covered. Then after some time messing back and forth -(not understanding which direction would make it hotter, faster, and or less or more efficient)- with the fuse of the machine. Eventually, the machine started to work as efficiently as it had inside my house but then the candy started tasting burnt which was not a problem before. So for the next 40 minutes, the machine worked great however the taste was not as good as it was when I used it personally before. Then the machine started to smoke and so we turned it off. Quickly following was a black goo of boiling sugar that started to rise and flow out of the machine's head like a volcano. It was something that had never happened to me before and so It spooked me enough to put away the machine for the night. I had not attempted to use it again until the weekend before my next vending session about a month later. I, of course, cleaned out all the burnt sugar, carefully avoiding water or soap on anything electric that may cause damage to the machine. In that weekend the machine was working incredibly inefficiently, working 4-5 times slower than when it was working like it was supposed to when I had used it for personal use. Barely anything would spin and what was spun was extremely burnt tasting. The sugar that was stuck to the side of the bowl was three times larger than it should have been considering the amount I was making. On top of that, all the sugar that was shooting to the side of my bowl was overwhelmingly noticeably burnt. After 20 minutes of attempted use which brought me nothing but about 4 cones of cotton candy which all tasted awful, the machine started smoking and boiling up like it had the night I was vending with my club the month before. I was very frustrated. Messing with the fuse this time didn't help me, and when I cleaned the machine again the same thing happened once I turned it back on but after producing much less cotton candy in the same amount of time. It's not spinning webs as It used too and I'm worried my 200$ investment for my club will come up to do nothing for charity after I barely covered the cost of the machine the first and only night my club had made and sold cotton candy. The machine just simply doesn't work anymore for some reason. ----------------------------------------------------------------Problem: The head spins but webs barely or none at all get shot out. All that is made tastes extremely burnt no matter which way the fuse is turned to. And now after only 15 minutes of me running the machine and putting candy floss in the head of it the whole thing will start to smoke and candy floss will start to boil into this black gue which is unspinable and becomes impossible for me to spin anything more without cleaning all the goo out.. PLEASE HELP.
