Thread: Help please w/ timing light operation.....

Tweet

Usually the retard advance knob is used in applications where the timing is locked,special disributor where there is no vac advance used primarily in racing to allow you to start the engine easily or where one is using racing fuel one day and regular gas the next or is usually used on blower apps for the street that run multigrade fuels,from 100 plus octane down to 89 pump gas and also n2o injection soo you can cruise at regular tinming and then use the n20 with a knob dialed back,then return to normal timing when the n2o is off.
A advance retard knob with regular distributor,mechanical and vac advance is usually a tunning nightmare and a sure fire motor destroyer
I personally do not like the idea of being able to destroy the motor at a turn of the knob which is easily accesed from the drivers seat
The unit itself only retards timing,that is why its usually set to the max timing with the knob in the max position allowing you to fully advance or to retard the ignition from the seat.
Set the knob to max and set a max timing setting then retard it with the knob to a more resonable setting,or if you are running the track set it at max for the track and fuel you are using,then use the retard function for pump gas.
For a street ride I would turn the knob to full advance and set the timing to non motor blowing setting,then retard the timing back to normal everyday setting.
Theres lots of possible uses for the knob,it just depends on your set-up and what you want to use the knob for.............I would try to camoflouge the button because its a resonable cause for a Officer to investigate for n2o which is illegal on the street here in cali.The ricers have made the retard knob a sign of n2o in the cops eyes and they are trained to look for the signs of n2o because they get to impound the car and auction it off.

Go over your engine set-up again and post this and the intended use and I am sure those who know lots more about this than me will know what you need to do to have a happy engine.
