I was told that a 12 horse tohatsu and a 15 horse nissan are the same , is that true ? I'm looking for a carb kit for my 12 horse but I can't find anything. Its dumping fuel pretty good and the needle valve looks like it has a groove in it . if I close the mixture screw all the way it'll slowly die out and when it does you can watch fuel pour out of the nozzle right inside the carb barrel. Im assuming the needle is bad . Any insight would be greatly appreciated
