This isnt how you get people to help you out buddy. The way you solve problems is by thinking of everything that can be a problem even what you think it cannot be. Not taking peoples advice and telling them you are getting pissed at excessive advice will get you no where. I was in the same boat as you were when I was your age. I got a Banshee that was a POS when I was 16, it ran for a couple months then everything went wrong with it at once. I didnt have enough money to fix everthing, so instead of being impatiant i let the thing sit for over a year while i saved money and read every single bit of information about quads on the web i could find so I could rebuild it right. After i graduated I got a job for a year, and then I was able to rebuild the entire machine into a harbinger of fury. So I reccomend taking a few deap breaths, accept that you cant ride this weekend and slowly and smartly go over the bike to find the problem so you dont waste money on things that arnt problems.
So that said...
You have had someone offer you a CDI to test, try that. Get a real compression tester, try that. Did you try to push start it, you can spin the engine alot fast pushing or pulling it than kicking it? Did you use a new gasket when you put the shaved head on, the head gasket could be blown? Have you tried new plugs? Gas is in the line, but is it in the float bowl? Is the pilot clogged? Sorry to offend you if you have already tried these
