Agree with the others. Lower o-rings are likely pinched. To evaculate the gas you can just leave the plug out and crank it. Stand back as the fuel will shot out. No smoking and don't do it if the engine is hot at all. You don't want to run until this is resolved as you will fill the exhaust with fuel and it will smoke like there is no tomorrow. If you are already there you can just burn it off then change the oil as well as is likely has fuel in it. Also check the other posts for fuel pressure test check procedures.
