Ok ! I give up !
SWMBO complained this was over running into the pan.
I got this - I remember !
Turn the white plungers set the depth - no problem .
After 20 minutes of swearing I give up . Either it’s too stiff and won’t plunge or enough but it over runs .
There appears to be no happy medium .
Notice the left plunger ( big poo one ) seems like it’s had to much beer and can’t get an erection , very limp
