I had given up on my GH with it's spotty performance and difficulty getting it to stay blue for long enough. It's almost 4 years old, no RMA either.
I spent a few days working on the back end and cleaning the threads but what works best is just twisting the back end until it works. Mine does not feel as smooth as it was when new but it is working again and pumping out vapor!
Lots of twisting, pushing and pulling and banging the clicker on my leg seems to have done wonders!
Also have a new back end on order.
Grasshopper thread is way too long now. I gave up, but I've still been having problems with my grasshopper... so it's great to have a resource like this to consult before having to contact GHL for a replacement/repair. Great resource for Hopper owners, keep it up!!!
This stuff rocks, Vapor Eyes!! Removes a large amount of hopper-related angst, for sure!! The FC community proves that the internet can be good for something. I don't really have much else to say but I'm not allowed to submit a review until it's 200 characters, so...
