In my case the next step will be a MSD ignition system. I would also check your connections at the coil since they also can be brittle. I seperated the wires and the car seems to run again and the tach works. The insulation is hard and brittle from heat and age. I found that the four wire plug that comes out of the Duraspark box had about two inches of insulation off of all four wires and they were touching. Luckly I was close to home and babied it there. Car ran but when the engine got up to around 3000 RPMS (by ear since tach was not working) the car would miss badly. Hard shift and then the tach never moved off of 3000 RPMs. & is there a High performance replacement for the fatory one

& What I want to know from you guys is.ġst.Would that hard 1st & 2nd gear launching down the street cause this? & wahla! it started up & I drove it home With out any problems.

& tapped it against the outside of the box. So being I had no Tools I grabed a breath mints tin. I then checked for spark.I was in the Dark with no tools or even a flash light! DOH!Īs I sat there feeling around for loose wires & such, I remembered that That another old 4 eye ( '83 I think) I had, use to always burn out the Spark box.( I must of replaced it 3 times. I thought I might of heard a slight poof type of sound & then it cut out.Engine died. I did a 1st & 2nd gear red line launch! But then. I think thats what its called its the silverish box that sits on the fender well & controls spark.Īnyways last night while leaving work.( & Showing off )
