RE: Serial numbers...
My service manual (available at amazon.com- $40 + shipping and taxes) lists the serial number breaks as follows:
1000004 thru 1199999 are the early models with breaker point ignition.
1200001 & up use the CDI ignition system.
Not sure why Honda had trouble with your serial number. It is 7 digits as they all are and falls within the early model range. They still service many of the replacement parts although many are now out of production. For example, the ignition points, ignition "condenser" and the "matching" ignition coil are all listed as obsolete.
