So I lost my leading spark today. Started running poor yesterday excessive noise, but was still working until today. I pulled over soon as i noticed my power. it was idleing poorly and missing at about 400 not 4000 rpm. I swapped my trailing in its place. power, idle and sound back to normal now. but obviously I lost use of the tach as I've been warned of already.

so my question is can I run a gutted ignitor till I can find another one. I don't care about trailing even though it backfires more. I just want a tach so I don't shoot flames every time I shift. Or what gm hei part number do I need.

 

I don't use a gutted ignitor anymore. Too much work. Find or or file down some small male quick disconnects (you want .110" size), push them in and bend them up to tie the wires into the stock harness. Been doing this for years.

 

Like this:



You can grind it, file it, or use side cutters to make two quick snips.

Wiring for MSD, they go green to red, purple to green, comparing the MSD wires and the pickup wires under the distributor.

After plugging the wires in, I bend them flat to the distributor and use the cap holddown to keep the wires in place. Never ever once have had them work their way out.

 

Exactly. Never had one fall out.

 

I scored and found some ignitors at You Pull It. Got to the car and it had no dizzy. but it was sitting on the hood 3 cars down and had both igniters one was mint the other kind of beat up. I snagged them both. Also got a new MOP or OMP, and a clutch fan. all for about 30 dollars. good stuff.

But I was being lazy and didn't disconnect my battery when I was pulling the alt and the wrench fell on the positive post and fried my main fusible link. Found some fusible link but I cant seem to find the right size female quick disconnects. Anyone know where I can find some of these. I've gone to shucks, napa, autozone, radio shack, ace, mikes auto parts. and all had the .0250, but nothing bigger. I ended up using the females from the old fusible link and but splicing them to the new one. I'd like to have this not jerry rigged.
