Stumbled across this forum, hoping someone will have some experience with this. I just bought a used nissan NS40C 2 cylinder which doesn't have a pee hole, and I'd like to add one. Anybody ever done this and can tell me exactly where I'd need to tap into the cooling flow to run a line out the engine cowl? I realize I could take apart the cover where the cooling water flows thru, but I'd rather not if there is anyone out there that can pin down the location of the tap for me. Thanks!
