Identifing screws on bottom of engine

[Dmwelch]

Hey Guys
So I made a bone head mistake and took out one of the screws on the bottom of my engine thinking it was the rain plug.... I know rookie mistake.

Engine doesn't want to idle correctly and then die, any idea what these screw do? And anyway to fix what I did ?

Check the photos out, I'm pretty sure I took the one that's recessed


Thanks

It's a case bolt. Did you re-torque it after? Should not really do anything if you had put it back.

Yes, if it was a bolt any longer than 40mm it was probably for the case! Looks like one of the central ones so it probably wouldn't be such a bad thing. Did you mean drain plug by the way? I was thinking, "oh cool these engines have a plug to drain water?" then I thought a bit longer..... and that would be silly
