If you can show me where to find one. Except, I do own a 1942 > Gravely that has points in the magneto - never used a timing light on it > - always followed the book on statically timing it. Yeah I haven't put a timing light on a small engine much either and I'm not sure if points and magneto behave the same as points and coil as far as wear patterns. > > > Or > > just observe the gap of a worn set of points - is the gap wider or > > narrower?

Well i did say observe not use a feeler gauge. Also i expect to some extent the metal transfer also produces some porosity which takes up more space than the original metal and may account for some of the closing of the gap. -jim > > >> That's my buttal.

That was my impression, though I admit I haven't researched the issue thoroughly. -- The problem with socialism is there's always someone with less ability and more need.

It wasn't a >problem because a huge effort was committed to fixing it in time. Yep. The fact that those in the business knew it was coming long before the public caught on didn't hurt either. Now the "general wisdom" is that Y2K was a "boy who cried wolf" scenario, when actually the wolf DID arrive, only to find wolf-proof brick walls and cranky called-out-of-retirement COBOL programmers with shotguns :-) (they're mostly safely back in retirement now, in a better position for the Y2K money...) -- The problem with socialism is there's always someone with less ability and more need.

And said fix will be a bulb which relies on the incandescence of an electrically heated metal filament immersed in an inert gas sealed in a glass envelope. Sure, it uses a little more energy, but it's SAFER, and more ENVIRONMENTALLY FRIENDLY don't you know :-) Unfortunately GE gave up their research into high-efficiency incandescents. I think Phillips is still working on theirs, though, both the quartz-capsule HIRs inside a standard bulb envelope and exotic filament treaatments. -- The problem with socialism is there's always someone with less ability and more need. |
