Hey Bob- thanks for the reply- I did check the spark with a little spark
plug checker gizmo- and it is getting fat blue spark on both sides- I
had put in new points and set the gap before doing the timing, but I
will do some switching around tonight to double check.

Check the spark on both cylinders. Pull the wire off the cylinder giving

problems. If not much happens try the other side, engine will probably
die. Could be bad wire, resistor, plug, cap, etc. Just something else to

look at. Does the points open evenly on both lobes? May be more
electrical than mechanical.

On one of my newly acquired Eldo's I am having this problem - I first
noticed it when tuning it up and running it for the first time- started
to notice smoke on one side, and the pressure from the exhause was not
as strong as the other side- figured rings or chrome bores peeling as my


first thought (although there is no odd noise coming from the cylinder
in question)- pulled the heads- found very uniform deposit on head and
piston - dull black soot, not oily, not shiny- valves and valve seats in


great shape. Pulled the cylinder- ring end gaps all to spec, rings all
in good shape, cylinder walls in great shape, no scoring no peeling. Ok-


put it all back together- re-check valve clearances and timing, now turn


attention to carbs- slide height identical on both sides, cable tension
adjusted, all passageways clean , needles look good, same jets on both
sides, choke is not stuck. still having the problem.

What am I missing??? Any input appreciated.

Thanks,

Brian
