. There are a few things you need to make sure of. First, the screws in red cannot be too tight. Second the spring in Blue may need to be shortened so it forces the Gates back. And third play with where the spring circled in purple is placed on the outside plate. I had to make sure my screws were loose, and I had to cut my spring in blue to make it tighter, that worked great for me. Now even my 110 gate works every time
. Make sure you mess with it out of the machine, and upright. Mine worked fine laying down, but then didn't for some reason upright. That should help.
