Re: Anyone install an MSD on their Howell TBI??
i installed my Howell last month and did not see a filter or embedded circuit board in the harness. I was under the impression that the filter was used to flatten out the multiple fires into one pulse. and i guess maybe clamp the voltage spike.
If you can describe what it looks like. I can find it and could post a picture.
FYI, the guys at Howell said they would send me a tach filter free of charge if I decided to upgrade.
