Short cycling on two stations only

[S_hannon]

Irrigation Question- I have deep water well. Sprinklers in front and back. Have old rain bird "clock" like timer with 7 stations. The sprinklers in the front yard come on and I can hear the well pump running. The sprinklers in the back come on and the well pump short cycles about every 8 seconds on and off. Had well guy come over today and adjusted the big spring in the pressure switch. All it did was increase pressure and busted my water hose. Still short cycling. When he left I adjusted it back to where it was. Any ideas what I should do next? It does have a blue pressure tank and 6 old valves with crazy wiring. Any advice is appreciated.
