Jon, I dont think the Mag is hurting anything,,, only thin with a mag is the base timing always stays the same all thru the rpm ranges, its slower reacting than the distributor,, but, still can be dialed in pretty close! They like the timing to be retarded to make good power,,, (on distributors,, rotate the distributor clockwise) till they sound like they are under a slight, ever so slight load at idle,, but, thats with the distributor,, mags,, may be the same, if you can turn them enough on the housing, to change base timing. Make sure the bolt torques are good, valve lash set properly,, or to peak cyl pressure,,, BUT,, if the engine is still fresh,,, (less than 10 hours) I would belive that its not fully broke in just yet. Cyl pressures fluctuate so badly till the rings seat that its like chasing a ghost when your tuning them in. it will be strong, then drop off, and likewise,, if its still fresh,,, go work it for a while, the more time they get the better the results will be, and less of a headache to tune.
