Hello... A few more questions... When setting points at 18 thou ( as recommended in many manuals I get a dwell angle of 35 ish If I drop gap to about 12 thou I get 46 dwell angle.. I believe we aim for dwell of 45-50 Should I assume I am poorly setting points with feeler gauge and accept dwell angle as correct? Or other reasons for errors? Also, clarification of my thinking please ..... When setting the points and locating the high point of dizzy cam, should this high point alsoalsobe be showing TDC. I.e..zero degrees on timing scale or about 8 degree BTDC? Or are dizzy cam and position of timing scale not relevant Thanks as always..
