I don't know if it would help to add that running at 18 fps, which is marked in red, is 28 seconds.
Seems to me that recent Bolexes, above serial 100401 with the desirable register claw, will shoot 16 feet on a winding which is about 27 seconds. I think the old ones with the unsteady cam-driven movement would shoot 19 feet.
Your speed dial is way off.
The cutout gears that govern how long the spring will run are mistimed.
Maybe the spring is weak so someone mistimed these gears on purpose.
Let me guess... you bought it on Ebay? :-)
Use a stopwatch and count how many frames go by in 10 seconds then divide by 10. This will be a good guide to whether the speed is correct or not.

This helpes exposures be more correct.
A local tech told me that it is the speed governor that goes bad. I asked him why he doesn't just slap on a crystal sync moter and bypass it. He said it wasn't worth it??????? One of those moters would be a good thing I think.

I noticed on the speed dial that someone etched a line into it between the 18 and 16. I just thought it was some kind of...I dunno...marker, but it ends up that that is the correct 24 fps setting.
What I did to test it is like you said, except I reset my frame counter to 0, and ran it for 1 second, see where it ended up. And lo and behold, it was approximately 24. I read someplace on the internet that a bolex improperly stored (that is, not wound down) will really ruin the spring motor and since it's more costly to repair the spring(?) it's better to just adjust by resetting the marker on the speed dial.
Thank you for your advice.
