Stevens Timing Tool

Post by A Whiteman » Wed Feb 01, 2023 4:10 pm

Has anyone seem one of these or have them in their collections?

It looks useful, but did it actually work? I would think NOT to use this when the engine is running as the little ball would be a blur to see I guess.

But could be a bonus when turning over slowly as that would show both TDC and spark firing in one tool.

Cool tool! It almost had to utilize a piston against a spring calibrated to a new compression pressure. Weak rings or leaky valves and I doubt it worked as intended. Nevertheless a neat idea.

They are for moving the crank slowly by hand to find TDC and timing.

There have been several fancy doodads to set timing over the past 100 years. Currently Lang's sells one that even lights up (for $87). They are all less accurate than going by the pin position, which has the advantage of costing the perfect price — nothing. https://dauntlessgeezer.com/DG97.html
