Pickup Coil/Reluctor

[1sttvbn]

So we all know to keep the Gap at recommended settings (.008 on my 340) My problem is (New Distributor) I can drive the car a few month's, and then it will start getting harder to start. Then I know the pickup has moved away from the reluctor, and it's time to re-gap. My friend said try using blue loc-tite on the set screw. Has anyone ever tried this?

Does your shaft have play? I know it's new but play may give a different reading each time. I've never had an issue with the screw loosing up. I wouldn't be afraid of some loctite or a star washer. I had hard starting issues from play in the shaft before. Drove me nuts until I finally figured it out .

I set mine at .010 and never had an issue.
