anyone used one of these before?
To roughly balance the twin carbs without a rr should be relatively easy. Basically just get them all level with each other until I can set it up propperly on a rr. But does anyone know what they should be on when I have it on a rr so that it's perfect. It has lots of things on it telling u if theirs a "late valve timing or leak at intake at intake manifold or heat riser" or "late ignition timing" for example. I don't have a clue how to use them, looks a decent piece of kit. Anyone have abit of knowledge about these? How much are they usually? Probably can't even buy them looks that old, digital now? Can I perfectly balance the carbs myself with it once i get it on a rr or is impossible to do myself?
