I have a Kazuma Falcon 150cc. Installed a new carb and changed oil 2 weeks ago and it's been running great until last night.... it started spraying oil out of the fitting on the front/top of the cylinder head. It starts up and idles just fine, no oil coming out. But when I increase throttle after about 2-3 minutes of idle run time oil then starts spraying out. Any ideas what is causing this oily mess?
