Hello
Can anyone give me a hand to set my max ignition timing.
Mini 998cc stage one kit
1989 mini
Sent it to aldon to get rebuilt.
They said 32 degrees max 5000rmp.
I have a timing light with the dials on it for advance timing I belive.
So I understand that I have to block the vacum pipe.
Bring idle to 5000rmp
Turn know to 32 degrees.
My question is is it zero pointer to mark up on the notch that has to line up?

The large pointer?
Thanks for any help

With the advance timing light you turn its dial to the desired value (32 degrees in your case).  Bring the engine up to temperature, plug the vacuum line, and use the idle screw(s) to bring the engine speed up to the specified 5k RPM.  With the timing light set to 32 you turn the distributor in the block until the ZERO marks on the front pulley line up.   

 

Don't assume 32 is fully correct.  After setting the timing set to 32, return the idle speed to "normal" and take the car for a test drive.  Accelerate uphill in too high a gear listening for pinging and knocking.  If you hear any bad noises, return home slowly and get the timing gun out again.  Determine what the idle advance is (point the gun at the timing marks and turn the knob until the zero marks line up at idle).  Record what that advance was and what the idle RPM are.  To correct the bad noises, retard the timing about 2 degrees from what you measured (this can be done at idle speed).  Then repeat your test drive.

 

The 32 degree value you were quoted may not be ideal for your particular Mini due to its general engine condition and the grade of fuel you use.  Be flexible.

Thanks for your advice.
My distributer is a standard one which had points
I sent it to aldon in uk for a rebuild and I had fitted one of there electronic ignitor kits.
My car has a standard engine with a mini spares stage one kit.
They gave me 32 degrees max 5000rmp figures.
what would you recommend?

you want the most timing you can pull without pinging, 32 is a good place to try but like dklawson said, be flexible. Higher octane fuel will allow for more timing, so if you don't mind spending a bit more at the pumps its a simple way to pull a bit more timing safely.

Thanks I will try next week after easter.
Thanks again for good advice.👍👍👍

I doubt you'll be able to run 32degs on todays fuel, but you may get away with it on a standard engine, as above try and see?

[cristiano1968]

Ok I will give it a go👍

[cristiano1968]

Went to try it today but rained.
Got a look at my distributor code and it's
41907a
.59d
-0990.
Any one got any info on this?

[KernowCooper]

If you sent it to Aldon for a rebuild and they said 32degs maximum advance @5000rpm then one would assume Aldon also have the correct weights and springs so the original spec would be the same
