My 75' Yamaha DT 175 dirt bike engine turns but wont start? - how to clean my dirt bikes engine

The spring again, and I felt that my bike this weekend. I cleaned the gas and a new candle. One side note, my work kick-starter. When it came to lead his country, he broke the clutch on the engine, a powerful explosion of sparks started coming from the shawl. The engine has good compression, but I'm not sure what could be the problem. He ran very well last fall, when I rode the last time. Any help in solving this problem would be great. I think it could be that his guilt, but in was not secure. Thank you.
