HERCULES IXLB5 IGNITION

NEED INFO & PARTS I have a " IXLB5 --4 CYLINDER– HERCULES" gas engine, serial # 246612.7. My engine needs an ignition and water pump system. The engine block casting # is 71452&746. I have been told that it was manufactured in CANTON OHIO, in 1952 and sent to BAKER FORKLIFT Co. in Cleveland Ohio, without a magneto, distributer or water pump, that Baker installed their own ignition and water pump system. The engine casting opening leading into the flywheel, where the ignition system goes is 2 7/8", on most Herc of this type this opening is for a Wico Mag and is 3 1/8". I have been told that the ignition system may be somehow tied to the water pump. I need info and parts. HELP. JIM E-Mail at jasi@saber.net, call collect 707-459-2649
