How do I Get the crankcase Cover off

once again thanks for the quick reply. and to answer your questions I just bought this quad a few days ago and they were using oil fuel mixer 30:1 I believe. and there is a metal piece that rest against the inner casing so the mechanism doesn't over shoot. I feel the kickers spring is working because it will return to half way once you try to kick it down. just wnot go down all the way.
 
Double check to make sure they did it correctly by viewing this thread, and make sure the carb inlet is capped off http://www.blasterforum.com/do-yourself-20/how-install-oil-injection-block-off-kit-681/index6.html

the pic shows what should be capped off on the carb
