Foam cannon with Karcher K4

[Sherif]

So today I tested my new MTM foam cannon (not from Autopia) it came ready with brass adapter for Karcher quick connect and I used it with K4 model (1900PSI / 1.85GPM) with CG honeydew and got some nice thick foam but it kept cutting off every couple of seconds and no contentious steady stream!!
After a quick search it looks like the problem is on the PW (back pressure cut off) but I don't know how to fix it because I cannot control anything on the PW, only On/Off switch is there!
has anyone had the same issue? any idea how to fix it?
:help:

Adjust the pressure/pattern on the mtm foam cannon. Think it's related to the pressure from the spigot. That did it for me.

Also, make sure your spigot is opened up all the way and no kinks in the hose.
