srobscopic timing

[minigreen94]

please could someone help with ignition timing on my 998 ,286 cam, soon to have a cooper head. but for time being i need to time it with the light with standard head on, while we build the other head. just needs fine tuning now after rebuild.
is each notch 4 degrees on timing cover????
thanks.

I think each notch is 3 degrees.

you need about 28 degrees total advance on a mini 1000, so look at the number stamped on the advance weight in your dizzy, double it and minus that from 28.

what you have left is what you should set the static timing to.

i.e '10' stamped on the weight x 2 = 20, 28 total minus 20 mechanical = 8 degrees static

then, if everything is right, you should be in the ball park for it starting and stopping.

if it then struggles to start or wants to run on you can then tweek the dizzy a little to help (though of course you can only turn it one way, so if it struggles to start AND runs on you need to start altering the mechanical advance in the dizzy!)
