[TR] Tuning after rebuilt dizzy from Advanced Dist.

[Greg Perry]

Craig,

Since you have a working rebuilt distributor, I would use the vacuum hose between the distributor and carb.  I run my 72 TR6 this way since the thermostatic switch quit working years ago. The vacuum retard only works at idle and starting the motor.  One plugs the vacuum retard when setting the timing with a timing light at 800- 850 rpm  to 10 to 12 degrees before top dead center.  Or leave the vacuum line connected and adjust the timing to 4 degrees A.T.D.C.  I usually set the timing around 12 degrees B.T.D.C.

Regards,
Greg Perry
