'84 40 horse:
I'd turn the idle down till it was just barely running, then twist the dizzy
till the rpms perked up. Turn the idle down some more and twist the dizzy
some more. Could usually get it to run around 300 rpm. Then turn the idle
back up to 750 or so and consider it done.
Dunno if I was doing good or not, but it seemed to work pretty well.

| Thanks for the reply.
|
| I recall now that I used to 'retard' the timing on my vehicles when I
|went from Jackson Hole down to Baja..
|
| Since by the time this hits the list it will be Friday....
|
| I never had a timing light but I was a pretty good retard...er.
|
| So the way I timed my little air cooled VW and Porsche motors was with
|Zig Zag rolling papers. First, of course, I had to use them for their
|designed purpose and then I'd get to the timing part.
| You could stick a paper between the points to see when they opened. I'd
|set the flywheel pulley mark at the right spot and then rotate the
|distributor till the points were closed, insert the rolling paper and re
|rotate the distributor body, pulling gently on the paper. When it came
|loose, the timing was on.....enough. Then you'd clamp the distributor in
|place and turn the motor back a bit, pry the points open and stick the Zig
|Zag paper back in there and re-rotate the big pulley...gently pulling on
|the
|paper. If it came loose just as the little notch hit the case seam...that
|was TDC...
| My 36hp bus was especially sensitive to timing, for some reason. It
|would
|often over heat on hills if the timing wasn't carefully adjusted. When it
|overheated it would just seize up solid...the back wheels would lock up and
|I'd clutch it over to the shoulder...and get out the Zig Zags....
| After it cooled and I'd used the rolling papers...It would fire up and
|we'd just drive on, no harm done...
