Thanks Speedy,

Those modules are exactly the ones I have. The new generic module is like the one with the spade connector and the other is the one from the full crank.

Let me see how I go with cleaning magnets, adjusting coil air gap, perhaps relocating the coil on the armature prong and swapping carbys. If I can get it to start easily, I really need another coil anyway as the one I have is missing a low tension spade connector although I have soldered on a wire.

While you have those modules out, it might be worth checking resistance with a multimeter. The new one I have shows 4.55Kohms while the old one is 6.55Kohms. 6.55 is supposed to be way too high but now I'm not so sure. If I can get it to spark well I'm going to try the old module back on. I suspect it will still go but only time will tell. It would be interesting to know what yours show.

Its not that there is no spark at all. There is sometimes if you really pull it over hard with no compression. Its been getting harder to start for years but would go if the plug was perfectly clean. The spark on my very reliable Powertorque seems much stronger.

Let me see what happens over the weekend. We may have a swap on.

Thanks

Jeff
