perry: I have already gone down to a 4.0 PV and it went richer.

Dave: if your using a "cheap two wire-unheated" o2, it needs to be very close to the head so that it stays hot. Mine is about 12 in from the head. Just weld in a spark plug bung.

Mine seems fairly stable; I would estimate +/- 50mv with no throttle change, when you move the throtle; maybe a 100 mv swing.

I'm going to try another 4.0 pv; hopefully the initial 4.0 is defective.

Guys, keep the suggestions coming; it's so rich I'm afraid to go more that few block for fearing of fouling the plugs so bad , it won't get me home
