Re: Help! The new VBM Domobar portafilter is not turning enough to the right

Could be the head gasket is to thick - if this has been changed recently put
the smaller sized one in, this assumes you put an 8.5 mm gasket, there is an
8mm one. My understanding is these are not manufactured to accurate
measures - so an 8.5 may work next time. They aren't expensive, so I
normally have several around the place.
