Here's your shirt
First thing first. Find the leak.
Air up the marker.
Pull and hold the trigger down.
If it stops leaking then it's a bolt issue. (#16 or could be a bad spacer or spring #13)
If it continues it's a on/off issue. (#22-23)
Replace packings accordingly and repeat. If it comes down to it being the bolt and changing the packing doesn't work, you might have to get a smaller spacer #13)
Do us a favor and take pics of the sear for us.
