MTW building pressure before firing

[Welsh71]

Any ideas what could be causing this would it be a bad dwell setting?  It splutters a few times then fires.  If I take my finger off the trigger and pull it again I have to wait until what feels like a pressure build before it fires.

Sounds like you're running out of air.Have you set the dwell?Has it just happened or has it always been like that?

I suggest you join the MTW owners group on FB,a plethora of helpful people on there.
