M28/11 + M28/12:
Timing is not set at idle but at 3000 rpm. With vacuum pipes detached it should read 26° at 3000rpm.
At idle, it should drop to 14° - 18° but that is just a check, the timing at idle is not important, it is in the rpms where you drive that matters.

I have the M28/12 Auto and it seems not to be running up to snuff like I think it used to, as I have not been driving it as much, and also don't have 98 Octane leaded fuel either. Found a place to get some 104 leaded fuel which I will see if that will run like I remember. Thanks
