Re: sea foam
Mix in a portable tank 3/4 gallons of premix gas, and 3/4 can of seafoam, (assuming you don't have the vro connected). Put the remaining seafoam in a spray bottle, run the motor up to temperture, remove the plugs, one at a time, spray some seafoam into each cylinder and replace plug. Let it sit 15 minutes, remove the air silencer from the carb while waiting, restart motor, and spray seafoam into each carb, until it start to stall. Repeat until the seafoam is gone. Run out the remaining gas. It will smoke like it is on fire, and drip goo on the ground. Replace the plugs with new ones. TD told me about this procedure.
