Hello everyone, i am new to this forum.

i have been trying to slowly restore a 1970 300 sel 3.5.

i had this car for the past 9 years, finally i have a little time to work on the mechanical side of it. i just put a new set of trigger points in it. it idles quite smoothly now.

however, when i step on the throttle for a little of the travel and hold it, it misfires and vibrates quite a bit. but when i continure to step on the throttle, it smooths out a little.

i have put new wire set, points, cap and rotors, and plugs in it.
timing is at 2 degree +, i have not checked the dwell, but i have move the gap back and forth to get it to idel smoothly.

i know there are many experts here, any advice will be greatly appreciated!
