Well you know what assume means.... "A__ of you and me". I assumed it would be obvious how to get out the old nozzle this morning and now I can't reach anyone at New Horizons on a Saturday. So... Anyone have any idea if the side sloping blocks need to come out to remove the nozzle? Do you guys typically bust up the old nozzle to get it out? I'm inclined to take a chisel to it to get in pieces since there is so much build up around the perimeter. Weather 65F today so perfect day for a rebuild. Any insight appreciated.
