hey guys

ihave a dm7 about a week ago to make it working one of my friends but alot of oil on bolt system and it was shooting great (i just had shoot 100 bals or less)

Today ihave re lubed it with dye slick BUT it doesn't work correctly The problem is that it shoots the first ball then a hissss noise comes out of the gun(for 1-2 sec) ..... if you wait till the noise gone gun will shoot the next ball if don't bolt sticks on its way and wont cycle completely(note that the first ok shot doesn't come from FSDO protection)

i raised Dwell to 22=same problem
ihave increased LPR pressure a lot=same problem.

so what to do?

note that before that oiling markers was working.

and something else the thing that mike said in one of his videos about Fuse bolt FLICK test ....i try ed alot but my bolt even with lube(ing much) doesn't pass flick test.

ah another question can i use Vaseline on hyper 2 regulator?

First thing id try is a good new battery

likely the battery.
relubing it with dow 33(dye lube) should help too.

you can also watch my video on how to set up a DM. The DM7 has a slightly different regulator so your LPR will run at an LPR of 4-5 rather than 2-3 like i say in my video.

Use dow33 on everything, Vaseline is too thick.
Check your orings too and look inside the back cap, something's binding up
