Moving on from this one to an 11hp in a Greenfield I fixed up for a mate last year, this motor is a bit smokey and I wonder if these are really worth re-ringing or not? Rebore and new piston is out of the question cost wise.For not much more than that I can put a brand new motor on it. I'm always suspicious of these Briggs because they can put a led out of bed so easily, and would be pretty annoyed with myself if this were to happen after a rebore. Apart from that the motor runs well with no odd sounds but is going through a bit of oil
