Golf 7.5R & Clio 200
If turning the lance on its side affects the mix and gives you a thicker foam then there is an issue with your lance, almost like you're not getting the draw of foam up the feeder tube into the mixer
I have had mine a little while now. Too long to mention it to CYC, think O may attempt to take it apart and see what's going on then, worse comes to worse I'll have to buy another.
Will be washing the 200 in a bit anyway, will picture my lance and foam, may even film. See what your thoughts are then
