I've been waiting for someone else to answer this post but, no one has as yet. If it were my machine I'd check the following.
1) change the fuel in the gas tank and the fuel bowl.
2) replace the spark plug
3) if gas is leaking from the carb. it could be because the float in the fuel bowl is not sealing completely. If so, you might want to check the crankcase oil to be sure no fuel has flooded into it. If fuel is present, change the oil, be sure to fix the float problem before doing this.
4) perform a compression check on the cylinder (possible leaky head gasket.
