^^^ What it says. Anyone know the cause of this? Is it a weakened valve spring or bad cup seal? Anyone? Anyone?

[neo71665]

either or, most likely a dirty or bad cupseal

[Phoenix Tear]

bad cupseal, replace it

or, it could be bad o rings. replace them and oil them.

I had the same problemmake sure your cup seal and o rings are oiled and in good condition, that was what was wrong w/ my silver bullet
