next time you have it out running around pull the lid shut it off check for leaks around fuel lines going to and from the carbs , primer valve assem. , fuel pump etc: alot of motors have zip ties holding them in place they get old and brittle . may not be it , but a good place to start . i personaly never had one leak out the carbs
Yeh my v6 150 does that, mechanic says its normal, theres a drain pipe designed into the bottom of the airbox to drain it back into the crankcase for that very reason.
