I haven't started my 7 in about a month in half to two months and I wanted to just hear the engine since I don't have an exhaust system on it really. Anyway, It took forever to start it about five minuets of turning it over. It would try to start but not unless I held the gas all the way down. I added fuel stabilizer to the gas since winter was coming in and I disn't think it would be started. Well I got it started and running, souneded like one rotor but ran for a few minuetes. Cut it off and pulled the oil dipstick and I got it witha ton of pressure coming out of it. What could this be caused by.

 

do you have crank case ventalation?

 

Is it ventilated through the oil cap spout. I ran a line from both pieces sticking out with a rubber line. I'll get a piece to vent it with and see if that helps out.
