This is the same setup that I have been using for 18 years. The carby is an SU HIF6 (1 3/4 inch throat) from a single carby Volvo 144. This version has an enricher valve (read "choke") that twin carb versions don't have. As a pressure operated carby it automatically altitude compensates (same as Bing used on Rotax and Jabiru) and also has a temperature compensated jet. The throttle spring is set up for wide open if linkage or cable disconnects. The piston slide uses a linear ball race for trouble-free operation. Depending on the level of engine tune the needle may need to be replaced. I find a needle code BAG most suitable on my engine. The manifold is actually from an EA82 engine which has the advantage of the water outlet being at the firewall end of the installation. It has been modified with unwanted coolant and vacuum pipes plugged.`The adaptor elbow is angled to keep the carby horizontal in flight. For sale due to clean-out prior to downsizing.
