Reply To: Howard Gem – JAP engine

[stuart]

The “correct” JAP engine for a Howard Gem should be a dry sump type engine (the fuel tank has two compartments…..one for petrol and one for lubricating oil).I have a Gem too but I cant remember what model the engine is called.It appears yours has had a conversion to a different engine.As you say its either a model 5 or 6.The magneto you require is a Wico and it should have an impulse coupling on it.
