A word of caution on using AI for engine info ⚠️
I had a call today from a chap asking what the squish test figure should be on his Rotax 582. It's not a race engine and it isn't something Rotax asks for in the 582 manuals, so I asked where he'd got it from. The answer was AI.
So I tried it myself. Google's AI happily told me the 582 solder squish test should be 1.0–1.5 mm, in bold, with a source link next to it so it looked properly referenced.
When I asked whether that was actually a Rotax requirement or generic two-stroke information, it admitted straight away that it wasn't in the Rotax manuals. It had borrowed the procedure from dirt bikes, snowmobiles and kart engines.
The worrying part is how convincing the first answer looked. If you didn't already know, you'd have no reason to doubt it, and you could end up skimming heads or changing gaskets to chase a number that doesn't exist.
AI can be handy, but for anything going into your engine, check the Rotax manual for your engine type, or give someone who works on them a ring. Happy to help if you're unsure.
