When I started there was always one guy that got all the carb work, and this was in several shops. Was trained on it, and did a lot, but then came the emissions carbs. Since then most of the younger guys (which means everyone) seem scared of carbs, but not as scared of them as they are a point/condenser ignition. My last ten years at work, put in exactly two sets of points. At home, prefer carbs and points to the newer systems, they don't take 500 dollars in parts to get them running.
