While they are out, I'mgoing to weld in an O2 bung and order a self contained wide band ratio meter. THat way I can see more accurately what is going on. The heat riser needs to be done anyway because I am realizing a lot of my symptoms could be caused by condensation of fuel before the head. Once I see how this affects things and I know my mixtures are right I'll revisit the distributor issue.
