[SEL] Another one lives./Update

Hi All,
         Some progress with the Maytag Twin thanks to suggestions from the 
list.
         Following Mark's info on the timing I removed the backplate from 
the other Maytag and fitted it to this one. (Should there be a bit of play 
when those lugs are lined up - maybe a degree or so either way ?) Where I 
had it set previously was definitely more out than this - probably about 4 
degrees retarded.
         I also fitted the muffler from the other Maytag (not a washing 
machine engine - this was a battery charger - I think Mark mentioned 
"Winpower Genset") and it really tames the little bugger down.
         I've started it up and also adjusted the governor slightly (about 
1/2 a turn anticlockwise to speed it up a little) - how sensitive is this 
setting? Until I get my rev counter sorted out it is difficult for me to 
judge. It has sped up a bit.
         I'm also experimenting with spark plug gap - the Briggs coil may 
not be supplying as strong a spark as the original Maytag coil. I 
originally had the gap set at 0.020" but am down to 0.014" now and there is 
a definite improvement. When I short out 1 plug the engine actually runs 
much better but this difference is getting less noticeable as I make the 
sparkplug gap smaller. Suggestions and comments welcome.
         It's still not running as smoothly as I imagine it should but this 
is the first Maytag twin I've seen so have nothing to judge it against.
         Another video taken this evening is here:

         This one is 30 seconds long (640 x 480) and is 2.85 Megabytes. 
(Reg, that video tutorial is getting closer - I used this as a test).
         Any comments and suggestions will be welcomed.

Keep the revs up (or down)
