Over the winter the set of 40 DCOE vintage Webers picked up along w/a set of 45 DCOEs last fall were taken apart, cleaned and inspected to see if rebuilding them was an option. The progression holes are the same on both carbs, there is no warpage anywhere and rebuilding them in the future should be easy.

Also mocked up the Webers on a set of Volvo Competition Department manifolds with a set of Swedish rubber mount/gaskets and Cosworth rubber vibration damping donuts and washers to see if the VCS air cleaner will clear the wheel well. It just clears, but it is too close so we will either fabricate a narrower filter element or have one made. The combo will however fit a 122s as is. A brace to the engine needs to be fabricated to position the rubber soft mount on the outside of the inner air cleaner half. The mount is visible between the carb throats and is inside of a clamp riveted to the inner housing.

These manifolds are for B20 engines and the ID is .250" to large for a road-going B18 engine. We can reduce the bore size of the runners in CAD and molds can be printed from this and can be used to pour an epoxy blend around them. This epoxy offers chemical resistance to gasoline, jet fuel, and alcohol and is used by NASA.

Also was pleased to find out after contacting the Volvo Historic Archive to get a copy of the information on file for this car that it still has both its original engine and gearbox/OD which means this is a matching number 1800s. This information is important to serious collectors, and purists.

The original 115 hp B18B engine with 10.0:1 CR will stay in the car, it is only three hp shy of the larger B20B 118 hp engine, first produced in 1969.

1967 1800s - - - 1968 122s Station Wagon
