1971 La318 Starter issue?
Well this is an embarrassing update. I recorded it to upload here, and when watching it myself I realized that it’s turning over just fine. I have all the plugs out so there is no compression except on the cylinder with the compression tester. Hence the occasional proper sound with whining in between.
I’ll go get myself fitted for my dunce cap later today. Lol.
Thanks for all the helpful input though, everyone!
