Hi everyone I'm hopping you all can help. so i just picked up a 71 ironhead and its kind of a mess. near as i can tell it has a bendix carb with just the idle mixture screw. when i crank it over it idles way to high and when you hit the throttle it bogs down and i get raw fuel out of the tail pipes. Im looking for proper tuning instructions with pictures if possible. also is this a decent carb and if not should i get something different? i new to Harley's especially old ones
