Question for the amassed knowledge on this site. I have dual stern guns in my Lutzow they have recently started acting up spurting and firing multiple times with a single push of the poppit valve . I have not adjusted them in any kind of way since installation when they worked beautifully for hundreds of rounds any suggestions of how something may have gotten out of whack or is it just time to adjust something. Thanks in advance Jeromy
First I would isolate the cannons to see if it is one specific gun. If it is a piston interrupter, try tightening the endcap on the base a little bit. Temperature swings and the spike in pressure caused by firing may have loosened it. Don't over do it, or the gun won't fire at all.
found the problem!!!!! had a piece of wire (like a single strand) jamming the spring on one of the guns. took me a while to get it back into tune after breaking them both all apart.
