Consider how much you pay a car mechanic for an hour of work. You're paying for the same kind of skilled labor to make a complex machine safe. It's not just parts, it's knowing exactly how to fix them right.

Are you sure it was the weather and not just a lucky fluke? My starter does weird stuff all the time for no clear reason. Last week it was super active on a dry day, this week it's slow on a humid one. It seems more random than anything. You probably just got the feeding ratio perfect by accident that time. People always want to find a pattern where there isn't one.

Yeah, we had the exact same problem at a deli last year. Their motion sensor would just die during the lunch rush. Swapped it out for a hardwired sensor instead of wireless, ran the cable through some conduit for extra shielding. It was a bit more work to install, but it fixed the issue completely. No more random drop-offs when someone heats up their soup.

Yeah, that's a great result, but I'd push back on calling it a "small" change. A new pre-heat protocol with digital tracking is a pretty big deal in a shop. It changes the whole workflow. A truly small change for us was just switching to a different brand of grinding disc for cleaning our joints. The cut was cleaner, way less chance of leaving contamination that you can't even see before the weld. It cut down on our porosity issues almost as much as your pre-heat fix.

Always spray belt dressing on a stationary belt before starting the engine.
