Did a search on this, couldn't find anything readily. I am working on getting my Puch to running condition as is, stock. 2 HP, High torque head. I'm not sure what size carb is on it, I'm assuming it is what came stock with my set up (12 mm?). Once running, I would like to switch over to a Techno Estoril pipe. What needle setting and jet should I shoot for to start? I know the old mantra, "jet it rich", but I want a ballpark to start with. Thanks in advance!
