Poor Autoglym foam cannon performance on Karcher K3 after upgrading the hose and lance
I was previously using the stock Karcher K3 lance etc with this Autoglym foam cannon. Worked absolutely fine.
Today, I set up using a better hose from the K3 to the SGS35 stubby gun I bought. I quick connected to the same foam cannon and it just shoots out the foam straight in aggressive blobs. No amount of tweaking the nozzles improved it. I went back to the K3 lance setup (but still using the upgraded hose) and same problem.
AI is suggesting the 1.2mm orifice on the foam cannon may be to blame and I'd need a 1.1mm instead. Can anyone please confirm this or suggest how to fix?
Thanks.
