I had that problem on the 5850 using a 3 gpm nozzle. Switched to a 4 gpm nozzle and the cycling stopped.

Pat, keep in mind that on the Delevan you are going to want full pressure. A pump should really be about 100 psi for staining with an ability to regulate pressure. I should be getting my order this week. I'll let you know how the little pump works out.
