After removing the snap rings, I usually shove the forward closure in further to pull the nozzle and liner out, then shove the forward closure out with a wood dowel.
Terry, I recommend putting a shop towel over the nozzle end of the case before pushing out a nozzle. Sometimes they can fly right out and this will help catch it from slipping through your fingers. After testing when the motor is still hot, often times I just pull the bulkhead out and the entire internals come out as one piece. If the bulkhead comes out by itself, then I put a dowel in the nozzle exit (larger than the throat) and push the nozzle and liner out the head end and onto the grass. The nozzle o-ring helps push out the grease as well.
I remove snap rings, pull the forward closure out, then use a broom handle/dowel with a rubber crutch/cane foot on it to push the nozzle out. The rubber foot helps reduce the chance of damaging the nozzle. Also, the broom handle is plenty long enough for a 76/13000 case.
