QUESTION: thanks for your answer, but i have a regina system with no egr valve. There are no vacuum lines to pull that i see to do this as the ecu controls the timming, i did unplug the idle contol valve and noted timming mark @ 12degrees btdc. when i hooked it back up timming mark was now at ten and a half degrees,and when the distibutor was moved in either direction no change. thanks
Answer Bill, Regina, you poor SOB. VBG Not a great system, but works. Pull dist. cap and line up TDC and then set dist. to slot/line cut into the edge of the top of the distributor body where the cap sets. That's it. No further adjustments possible.
Merry Christmas
