timing my engine...
Hello all.
In timing my engine (74 2.7), my pulley has a 5deg ATDC mark on it. I assume this is correct for my year even though it did not come factory with a smog pump. My question is, the idle timing adjustment, is this adjusted with the vacuum hose connected or diconnected? I have heard both. I am used to small block Chevy's where you disconnect the vacuum advance for the timing adjustment. Also, to adjust mixture, which way to turn allen key to lean the mixture (CIS)? I need to get a CO analyzer to set my mixture. What is the peoples choice for a stand alone analyzer? The car stumbles a bit when I drove it around the block. This was the first time driving this car since the complete rebuild. It seems to be really rich. Pulled a plug tonight and it looked wet. Mostly tan to dark brown on color. Hopefully I can figure it out so I can drive this machine soon. Thanks for all the help! Chris |

Chris:
I plugged my vacuum line permenantly and set the timing to Z1 (TDC) @ 900 RPMs. Runs like a scalded dog. If your car has a CDI unit make sure that the points are set to spec or .001 over.
