Do you smell gas in oil? Do you see water in oil when change it?
Gas in oil could be caused by
VST overfilling, have fuel system checked to make sure float valve in VST is working properly.
Over propped, should be propped so that engine is on high side of rpm range(5000-6000 range) best results is if engine turns 5600-6000 rpm's at full throttle.
Improper break-in, piston rings didn't get seated in during breaking, have compression test and leak down test run to see if engine is in good shape.
Engine running too cold, check thermostats are working properly and allowing engine to run at a normal operating temperature.
