Actually, I think it is already gone since application of vacuum to dashpot produces no movement of dizzy breaker plate. Somehow it is already locked down.

I keep wishing for one of those fancy timing lights with a degree indicator dial. Last I checked a couple of years ago Mr. Snap-On-Man wanted $400. Too steep. Short of that... Maybe I'll pull the pulley and make marks at every five degrees BTDC up to about 45. Then static timing light would do the trick for the whole dizzy operating range.

Was quite suprised to read in Volvo FSM that up to .008" slop in dizzy shaft is acceptable. That's a lot of variance in points gap and dwell. Fortunately my ol 145 dizzy seems to have maybe half of that for free play. Maybe I'll rig up an indicator and measure it exactly. Prior owner musta been religious about adding the required drippy droppies of oil each 10k miles in funny Volvo dizzy oiler feature (little knob thingy). I juiced it up good with my favorite mixture of Moly powder and Marvel Mystery oil. That should keep 'er going.

Later,
Al
