Distributor with no advance?
1966 F100 with a 240 engine. I was checking my timing the other day, and disconnected the vacuum line to the distributor. I increased the RPM to 3000, and the timing didn't advance. Reconnected the vacuum line, and advance was working. I assumed the weights were frozen for the mechanical advance. So, I removed the distributor, and to my surprise, there are no weights for the mechanical advance! I guess I have never seen this before. Does this distributor not have mechanical advance?

Thanks, I guess that means there won't be any advance without the vacuum line connected?

Just throwing this out there...wouldn't he get better performance from the truck if he swapped out with a 300 distributor? I know they talk about it on a 223, with some other mods to make it work, but it oughta drop in a 240 i would think.
