[QUOTE="Steve83, post: 139348, member: 2574"] The 1200 EFI case is not drilled for a coolant bypass. The coolant is routed through an air valve, which allows more air into the intakes to speed up the idle when cold. The coolant warms, the air valve closes, and the idle is slowed down to normal. This would be a perfect heat source for a single carb setup. In order to use an EFI thermostat housing with it's 2 extra ports (coolant temp sensor and air valve outlet), the stub at the front top center of the case must be cut off. It would probably be easier to tap a nipple into the original thermostat housing.
