Not even sure yet if i will end up with solex / Mikuni Triple carbs but, when i was ordering some parts from Japan and saw this set of Manuals for 10 bucks i just couldn’t resist. It’s a set of three Manuals / parts catalogue copies in high quality by Mikuni Kogyo corp and Tokiwa (Mikuni / Solex agent in Japan). This one even features a nice picture of the S20 Engine. Now also figoured out the same seller sells new sets with an additional Manual… Still have to read through it though. quite a bit busy atm and can’t find time to study all this stuff thoroughly.
