Swirl chamber
So my manual says: “Loose pre-chambers are harmless. Mount pre-chambers which have fallen out so that pre-chamber fixing screw slots into the recess on cylinder head.”
Not a big deal after all. Oh, this info was in my Pinzgauer manual, not the Green Book.
You should definitely take the chambers out because the two heads I am building both had caked on crap all over it! I can imagine that eventually you would either foul the chambers enough that the fuel spray is reduced to a drip or chunks of crap end up in the bore.
Thanks for the replies!
