Historical information

Early experience resulted in this motor being partially dismantled to investigate load knocking when turned over on the starter motor. Subsequently it was discovered that the "noise" was normal, a unique aspect of the 1830 engine. The engine was then re-assembled to an operational state using parts from stock.
