Re: oil leak from prop area-hep me!
2 cycle engines are messy.
The more you idle around, or if you have poor compbustion, or just by nature, they will build up unbunt oils and such between the upper engine section, and the propeller. In what might be considered the exhaust pipe section.
After running, and let to sit, these oils will drool down this exhaust pipe area and gather into a goo that will dribble out of the propeller when motor is allowed to sit in the propeller down position.
Now I did not say that you do not have a real oil leak somewhere.
If you are still uncertian have it looked at professionally.
The only other place that would have oils that might leak might be the gear case. If you service that, you will quickly either see it's full of oil, or the oil has been exchanged for water, or some combination there of. Leading to the belief of an actual issue.
Probably the best defense to the drools is a good state of tune followed by good hard extended use.
Probably the most disturbing is to start it on the hose and run at low RPMS in the driveway.
