Does anyone have much experience with the novarossi pre run engines? I recently purchased a flash 21 special pre run and the compression seems quite low (can turn the engine over by hand relatively easily). Is this normal or something to be concerned about?
My pre-run Flash PT .12 after 1.5 gallons still has a small mechanical pinch with tons of power. I will purchase all my future engines this way. Engines nowadays take forever to break-in.
Pass you soon...
