First, reset the LPR and HPR to 60psi and 10psi, respectively, if its leaking at this point, proceed to the next step, otherwise slowly increase the HPR until one of three things happens, The marker is shooting at 280fps, the leak starts, or the HPR pressure is above 400psi. Then pressurize the marker with the grip frame detached. Have a small bottle of water and soap with a dropper handy, start looking, listening, and feeling the hosing inside the marker for tears, leaks on the barbs, etc. 99% of all the leaks that I have had like that are from my 'cocker hosing going bad. A bad timmy solenoid will not usually leak due to the push/push operation, as opposed to the push/pull operation of an ego that will leak.
