-Remove the middle o-ring on your reg piston to disable your thumper's internal reg (jd used his internal reg for fine tuning, with the inline reg to keep the input from going over 300psi, and you might also want to try this if you're uncomfy disabling your internal reg, although it might become necessary later)
-Setup bottomline so you can use CA and run that to your reg
-Make sure you reg never goes above 300psi! more likely you'll set it around 250-270psi to get the right fps, but just make sure it doesn't get past 300psi or you'll damage the actuating valve
-Make sure to check all o-rings are still good
-Lube everything up (with light lube, not too much)
Air it up and go from there.
I like what you say, but why couldn't you fix the typos!!!
Is the most current new main valve out (the one you have
to send your marker main valve housing into metadyne to get it installed that we've been told is the ultimate fix) the gen 4, or is the gen 4 the last of those you didn't need to mod the body to install? Thanks woouulf!
