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 near Berkeley, CA '72 Eldo '74 Eldo '95 1100sport '73 v7sport project |
