Hello Everyone,
Okay, trying to set the timing on my '81; Emissons label says 6 BTDC, okay; start engine, disconnect 4 pin connector, check timing and its like 30 AFTD. Running really rough as well. I can turn the distributor CCW and get it to run better and closer to 6 BTDC, but that's not where the distributor was when I pulled it out.
I have put a compression gauge on #1 and bumped the engine with the starter; got compression and the timing mark is coming up on TDC, put the distributor in so that the rotor is at #1. (It can only be at #1 or #6 due to the cross pin in the shaft for the oil pump.) So it must be positioned correctly.
But when I start the engine and pull the ECM connector, the timing is still way off.
So HELP!!! What have I done wrong here????
And also my tack that did work, has now stopped. The tack filter is not open or shorted, so I do not know where to go from here.
Again HELP!!!
Thanks to all that respone in advance
