13 HP Honda Flooding with Oil

Watchung, NJ
Hey, looking for some ideas here, I have a 13 HP Honda engine on a pressure washer, and whenever it gets tilted during transport it seems to flood with oil. The cylinder gets oil in it, making the starter cord impossible to pull, the air filter gets oil in it, sometimes even the carb gets oil in it. I have to pull the spark plug everytime it happens and wait a day for all the oil to all settle back down. Needless to say, quite a pain. Any ideas on why this happens? I have another pressure washer that has never had this kind of problem. Thanks.

Dont tilt them.
As pugs stated above:)

OHV engines and actually all small 4cycle engines should not be tilted toward the spark plug side or with the plug at the lowest point, the oil from your sump will fill your cylinder and cause your issue. I would suggest strapping down your equipment during transport this will help greatly with this issue and any other damage that rolling around untethered my cause.
