On my '74 2.0, I can't get it to run right. It's gone through a restoration and put aside for 2 years. Now, back on it and it's almost done but[b] number 1 and 4 spark plugs are clean/wet and 2 and 3 are black, (after 10 seconds of running). What I've done so far: Rebuilt MPS, gapped points, static timing, set fuel pressure at around 27 lbs. Compession between 90 and 110. Plugs are sparking. All injectors spray (not sure of pattern). I believe plugs were new 2 years ago. They look new. It runs really rough, white smoke out exhaust and some mild popping. I though, maybe injector triggers but all are working from my, spray in the cup, test. Dizzy backwards? Any ideas to what's going on??
Thanks for any suggestions. |

You need to do all the basics. (In this order)
Check valves. If they are not in spec, set them. Do your timing (has to be set at 3k rpm) Do your dwell Change fluids (oil and gas) Do compression with a hot engine, open throttle. See if your number come up. 90 is near rebuild. Then you can worry about spark plugs. Right now you have no baseline. Get the basics done and go from there. Zach Ps: if your dizzy was backwards your car would not run and you would shoot fireballs out the intake. Fun times! |
