A .40 gap is kinda beyond huge, a .040 gap on the other hand sound a lot better  Autolite 24 plugs at .040 inch gap with your Pertronix will be OK. Points used .035 inch plug gap through the years and it would work just fine with your Pertronix also. Pertronix generally says you can open your gap about .005 to .007 with their ignition setup. |

I missed the points/pertronix distinction, Ken. Thanks for clarifying. I don’t like to be one of those guys that gives bad info. (Like 75% of the posters over on FB)

Thx guys. .040 is what we went with. Unfortunately it didn’t really fix very slight shudder at idle. Any ideas?

How about some additional info on the shudder you mentioned. Define shudder. In gear? Idle only? On acceleration? What rpm does the shudder disappear?
A transmission damper plate can clatter/shudder as well as the transmission gears at very low idle. JQ |

The shudder is at idle as your moving thru the no wake zones. WOT is no problem at least doesn’t feel like it. Boats flys at full throttle. Shutter is also present even if you push the throttle up a little but over the idle speed.

Mark,
The shudder - like it's not running on all cylinders? |

Sort of like that yes. On lake as I type. Again WOT it flies but moving slow at idle or even 3000 RPMs has a shutter about kind of shakes a little bit
