Tapping Sound on My Kubota L3902 HST

[Alex001wong]

I'm dealing with a funky issue on my Kubota L3902 HST. There’s this weird tapping sound coming from the engine, esp. when it’s cold during startup. It disappears once the engine warms up, but it's still concerning.

Anyone else run into this, or have any idea what might be causing it? I’m just hoping it’s not something major.
Thanks!

Sounds like it might be some slop in the solid lifters, maybe a quick valve adjustment will do the trick!

Also, you might wanna check if you’ve overfilled the oil too... just brainstorming some possibilities here!
