Thanks John, I have been thinking some more about what was wrong . There were two things I did with the distributor-one was to replace the capacitor.The other was that because I was concerned about oil/grease on the contact points, (even though I didn’t see any on them), it looked like the grease on the points cam follower had travelled. I cleaned both sets of contacts with brake cleaner then dragged some strips of dry white cardboard through the closed points a few times to remove any grease/oil etc. My problem is that although I knew I had installed some eBay ignition parts (NOS) to avoid poor quality, the shop may have replaced what I put in because they definitely did some rework in the distributor (filed down a peened fastener in the breaker plate which was close to dragging when it advanced, and soldering on a new terminal on a wire. I don’t want to question what they did because it was all fine work. I don’t want to offend the shop by questioning something they did. If they did put a cap in which went bad (unsure who installed it), so be it-they lent me the tools to find it! My lack of power boost returned and I am left with having to put a new control valve kit in as that is the last of a bunch of things I did which I didn’t!

That is how contact is made . By pressing can in . Truly Chinese junk . They are intermittant due to aluminum oxide inside , I cut one open . White dust all over the contact area . You are extremely lucky to find that . It took me years of intermittant hard start problems . Old mopar caps look bad but much higher quality . If you see those lines it is junk > > Sent from my iPhone > > On May 31, 2016, at 5:13 PM, Michael Moore mmoore8425@xxxxxxx [Chrysler300] <Chrysler300-noreply@xxxxxxxxxxxxxxx> wrote: > >> >> >> My 300H was running great.
