Re: very bad gas mileage.
Don't 'baby' the engine so much. It needs some WOT, wide open throttle, time during break in. Don't abuse the engine but it wants/needs some hard running during this initial period.
You'll probably start seeing a change in plug color after another few miles or a couple of gallons of fuel.
What fuel/oil ratio are you running. If you're going by the kit instructions that say 16:1 that has been determined to be too much oil. Drop your ratio down to 24 or even 32:1. I think you'll see a difference in how things perform.
