uhhhh, not enough cylinders? Sorry, no he's right about the low compression. Make sure you do a good break in, including winding it up (gradually) and letting compression slow you back down. Forces the rings to seat.

On the idle thing, is it quickly cycling: like a second of gas, then cut, over and over? I seem to remember mine doing that when I had a sensor or something unplugged...
