OK, this is dumb but here goes. On my 31 K I always assumed spark lever position was up for retard and down for advance (like Model A Ford?). But somebody the other day said that up was advance, down for retard. I run the car with the lever in the middle and it runs fine, but I'd like to have max advance for road trips. Up to now I have not found anything in the owners manual or service bulletins that specifically says which way it is. Guess you are just supposed to know. Once again, apologies in advance (pun).

My 29 L has engraving on the hub ring which indicates advance is up and retard is down. Near the top of the range it says 'driving range'. Behavior of the engine also says up is advance, as it starts better low, but runs better high.
