well my mechanical timing is set perfectly but i still cant set the ignition timing to the middle mark the best i can do is the first mark so 15 degrees btdc and thats if i adjust the tb to what it need to idle at. Its not the original tb bc i had to wire a map sensor and the tb has one on top of it. Also when i start it it idles at 2k but when warm idles at 700. Any suggestions
