This may not be a motor problem. It sounds like your pump is not working properly and the motor is just following the pump. First thing to do is check for leaks in the pump, wand hose, gun etc. It may also be a blown water seal inside the pump.

i believe the spring is the actual trigger spring that pushes the trigger switch back in place and the water leaking out is probably a seal issue

SOURCE: The motor keeps surging
If there's a lot of sediment in your water supply, there's a chance that sediment has gummed up the pressure switches. I'm assuming it has a full power switch and high power switch. It runs on full power until a pressure switch is satisfied, and runs on low power to slowly build the pressure back up, at which a second switch is satisfied from the pressure and turns the motor off. These things are not easy to work on, and are made of metal probably too fragile to try any chemicals. You should probably contact the manufacturer.

Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.
