Re: [TR] vacuum advance thumbscrew

["WBEECH" <wbeech@flash.net>]

Honestly I don't use the thumbscrew, I just set up a light and get as close
to 4 degrees BTDC as I can.  This will get it started just fine then you put
a timing light on it and fine tune with the thumbscrew from there.

The manual says that one mark on the wheel adjustment gauge is 4 degrees,
doesn't say how many turns it takes to get there.

Subject: [TR] vacuum advance thumbscrew

I've read some place that a complete 360 turn on the distributor vacuum
advance thumbscrew (tr-3 motor) equals 8 degrees of either advance or
retard, whichever is needed.  If I've set up everything TDC compression
stroke, pointer on hole in pulley.................(thumbscrew set in middle
of its range................then I simply turn thumbscrew half a turn
advance direction and I'm all set for start-up?

Just checking to be sure.  Getting
ready for initial start up here.
