I need a tach to set the engine rpm  for tweaking the ignition timing.
The tach in my van doesn't work - and one I bought at HF Friday night
doesn't work either!! As the Lil' Boy sez "With HF yuz pays yuz nickel
and takes yuz chances!" Fortuantely I can return this thing.

But to my other question - if the mark on the pulley is set to the split
in the case - and the distributor finger is set to the mark on the
distributor case - how close is that to the correct timing anyway? I
know there may be some minor variations, but are those base setting in
the ballpark sufficiently to drive this thing a bit.

Finally - it runs like crap when the Temp II is disconnected. Idles
extremely rough, barely runs, coughing and spitting. And frequently
dying. No way to get above idle RPM either.

Thanks,

John
