[jsayre914]

If i just did a valve adjustment on a 74 1.8l with l-jet, and i did not have a mirror handy. I set 2 cilnders to the red mark and the other 2 the po made a nice white mark at 180 degree(thanks)

now i have an adjustable timing light. What do i turn the knob to. since the red 7degree line is now 0.

am i f#$% up this job or what. i am learning... one blown engine at a time (IMG:style_emoticons/default/bye1.gif)

You blew it. You used the 7.5 degree mark for two cylinders and the TDC mark for two cylinders if I understand you.

The valves on any cylinder are set when the piston is on TDC firing stroke. That means if you lined up the white mark, you have to look at the dizzy to see what cylinder the rotor is pointed at. There are other methods ... search for Cap'n Krusty's method of valve adjustment.

When you time the engine, you use the red 7.5 degree mark or, as you said that you have an adjustable timing light, you use the white TDC mark with the timing light set at 7.5 degrees.
