To use the burette, I think a plastic plate with o-rings around the
combustion chamber is bolted on (on American racing motors, anyways). The
fluid is added through a hole in the plate and the clear plastic allows you
to see if the air bubbles are all out. Saw a photo of this once a long
time ago. Probably a specially made plate. The plastic sounds easier.
