Timing light, loosen the dizzy clamp bolt to allow you to move it, start car in test mode, once idle settles, turn the dizzy anti-clockwise till the timing jumps up 2 or so degree's, take out of test mode and do up the bolt :)

Re: Advancing timing??

if you are going to run straight BP ultimate or even (pokes tongue out) Optimax, you can get away with a heap of timing - base timing should be about 10 degrees stock, i think mine is up around 18 or even 20 - it was set on a dyno, and in test mode the car wont idle 'tidily' enough to get a proper reading, i only run BP Ultimate and no pinging :s6:

Re: Advancing timing??

I usually find it best to set the timing without using the light.
Each individual engine will require slightly different timing depending on condition, fuel, modifications, etc.

The best way to do it IMO is to do it 'by ear' - i.e. twist the dizzy with the car at idle until it runs att it's fastest. Then take it out for a drive. If it rattles under load, bring the timing back slightly and try again. Once the rattle is gone, this should be pretty close to the optimum position for your car.

Re: Advancing timing??

I adjust my timing much the same way 'mongrelEB' does, though I also use a timing light to see where the timing is.

Rollin -
I've found that Optimax, Mobil 8000, and BP Ulptimate all give identical results, anything less and pinging is evident. Even Caltex Vortex will ping, and it's only 2 points lower.

Re: Advancing timing??

so the real question is, is it worth advancing the timing, and spending extra on pulp?
