Well manual says 600prm is correct idle. Sometimes it idles perfectly and never dies, sometimes it dives to 3-400 and fluxuates up and down for hours. It will also blowback when we're boarding or surfing if it is acting up.
Carb kit w/ spacer gasket is on the way along with new dist cap and fuel filter/water seperator. Already replaced plugs and oil and oil filter. New gas. I did not know to use high octane non oxygenated and add stabilizer to every tank. I will start doing that.
