When my K7.1 unloader starts to go bad, it is slow in switching from bypass to normal spray. As it gets worse it stays in bypass. This happens after the unloader is 4 to 6 months old. I keep 3 or 4 new unloaders that I get for about $45.00 each, but hate to keep putting new ones on. I think the part that goes bad is the smaller spring in the larger part of the unloader. When I compare a new spring to an old spring it is 1/4" longer, so I have tried stretching the spring. This works for a few weeks then beging acting up again. They sell a rebuild kit for more than I pay for the whole unloader. Can I by just the spring from someone? Who? Thanks for the help.
