I have a 1996 15 HP Yam. Starts up easy, idiling is rough. New plugs helped a little. It does not come up to full power when running. Noticed raw fuel emulsion in prop exhaust when flushing. Any ideas would be appreciated.
Just got the engine, doesn't look like it's ever had anything done to it. I was just trouble shooting it and the #2 bottom cylinder is not firing. Getting plenty of fire through the plug. Pull the #1 plug wire while running and it dies. Pull #2 pluge wire and it keeps running. It's going ot the shop.
