Re: Weak Spark Problem
Make sure the coil wire is solid wire and not a modern carbon wire.
Hold the coil wire about 1/4" from a head nut and see if you have a strong bluw spark.
Stop the engine with the points open, then short across them with a screwdriver off-on, off -on, etc. to check for a good spark. If you now have a good spark, the points probably need to be cleaned.
You need at least 5 volts at the coil while cranking and 6 while running. If it's less, you may have loose or dirty connections.
