I just bought a DTI Tech Time 3300-s timing meter off eBay a couple weeks ago. I’ve read plenty of threads on this site and others saying that the probe has to be filed to fit or the bracket hole has to be opened up slightly. I went ahead and filed the probe slightly and it fits good in the hole now. However, I can only insert it without the radial spring. If I put the spring on, it WILL NOT go in the hole past the spring. I have tried everything I know of. Anybody have any other ideas? I have used a 5/16” bit by hand and even double checked with a mirror - the hole is clean.
