I have an old 010av, all orange, points behind the flywheel. I'm not sure it's worth getting going, but I'm exploring options. The issue right now is ignition.
I have removed & cleaned the flywheel, points, & plug, set the gaps on plug, points and coil-flywheel, pulled the ignition wire and let it spark through a screwdriver to the cylinder using two different plug wires. The spark is just plain weak.
If I pull the plug, connect the spark lead to it, hold it against the cylinder, there's not enough juice to jump the plug gap; tried with two different plugs. If I position the plug so the electrode is almost touching a cylinder fin, there is a spark but it's only able to jump a hair, not the 4mm quoted in the service manual.
My settings are:
Points: 0.4mm @ TDC
Coil-Flywheel: 0.2mm
Plug: 0.3mm
Measurements of the condenser and coil are:
Condenser: 0.179uF
Primary side resistance: 1.0 ohm
Spark side resistance: 8.0 Kohm
The points look good, no pitting, and I checked for spark with the condenser disconnected; it made no difference. Everything above falls in spec from the service manual, but the spark is very weak.
I would like to try a new coil, and/or upgrade to electronic ignition & lose the points. Stens has something, but it's $150, and the saw just ain't worth it.
Any thoughts, ideas, help, and/or obvious things I've missed would be appreciated. Thanks in advance.
