I'm tough, I can take it, so correct me if I'm wrong. It's happened once or twice. ;8^)
My impression was that all H4 mags are the same as far as their gearing. The ones that ran CCW were on the diesels and the 9-series gassers. But I'd thought that the reason they ran CCW was because of the extra idler gear in the timing train which would reverse the direction of the magneto drive from the rest of the letter series. Other than setting up the impulse to click in the opposite direction, I thought they were essentially the same for internal gearing. If the impulse coupler on Lanse's mag were set up for CCW I could understand his not being able to get a spark at TDC for starting, but it ought to fire when being pulled if everything else is in order.
Only other thought is that if his mag did come off a diesel or a 9, and even if the impulse coupler were switched for CW rotation (if that's even possible), those mags were set up to spark at 7* and 15*, far less than the 35* advance of the regular gassers. Still, I should think it would run, even if poorly.
