Dragonheart - What make of engine is it? I know of no 4 strokes that are ringless. All of Saito's aac and abc engines have rings. I don't believe a ringless 4 stroke with conventional valves and breathing will work, because of inadequate bottom end lube. So even though I agree with the instructions (I use that proceedure for all engines except the old iron stuff) be real carefull to not over heat that ring. Make sure it is seated good before really leaning on the engine.
