I tried to get my new engine going for a couple hours tonight and it just cranks, no fire.
Got fuel to the carbs, but no spark at the plugs (IMG:style_emoticons/default/sad.gif) Checked the coil and I get 12V off each side to ground, is this correct? What is next in the diagnosis...what else can I check? |

Unplug the points wire at the distributor. Now check to see if it goes to ground and then gets disconnected when you rotate the engine. It's easier if you rotate it slowly, possibly with the turn-one-wheel-in-5th-gear trick.
Does it get grounded and then disconnected? If not, then the points or the points plate or the ground braid are the problem. --DD |
