That's the 'DRY' test, putting a few tablespoons of oil in plug hole, if compression seems to increase some,
then it could be rings, if not valves. SlumLord told Tyler about Dan's Motorcycles' how to get a bike going,
lots of good info there. If there is spark but weak and timing is good, could be wires, if an old bike take coils
and put them in an oven on lowest setting for about 5 hours, I have brought magneto coils back to life doing
this. Dampness will kill a coil if not used much. what is condition of air cleaner? if dirty than engine is partly
choked, does starter 'basicly just do its job or does it seem to, you know, peel over like very little effort as
compared to being sluggish. If it IS a spark issue as he cleaned carbs an has a good battery, see if he can
get another coil, it takes time but I've done stuff like this, a coil can seem good when not hooked to a spark
plug you can get a good spark, inside the cylinder though, different story,
Just for the hell of it, put a bit of gas in plug hole, if she fires right over carb setting are probably off a bit, carb
can be clean but not properly adjusted, the ole 'gas in her plug hole tells a lot if she fires right over even if for a
few seconds.
