I took the carb apart twice, new spark plug, air filter and battery. This bike refuses to start. If I put a liitle starting fluid in carb it starts right up and runs great. Can the choke be bad, it only looks like a barrell that slides up and down?

 

Well I had an LT80, I dont know if the choke can be bad but if it is or can be bad then thats probably what it is. I could never start mine cold without choke....good luck.
