There is a situation where a "knock" can occur,
strangely enough it's known as "diesel Knock"
once heard never forgotten,
think a small ball bearing getting into the combustion chamber and belting around hitting the piston/head.
Chills my blood just remembering that sound!
Various causes from incorrect injection timing to excess fuel.
Or over doing the starter fluid on a bad starting engine.
I can't think how a new engine could suffer from this knock.
As stated try the guys at the L200 owners site.
you may not be alone.
