Sea Foam Spray for Yamaha generator cylinders [SOLVED]

Hello Jim. For my Yamaha 2000 inverter generator, what product do you recommend to spray into the spark plug holes and how much?

Hi Dale. I recommend using Sea Foam Spray for treating cylinder cavities. If using for storage preparation, a 2-second burst per cylinder should do the trick. Make sure you crank the engine a little before putting plugs back in.
