Alot of people have tried doing this as the genuine o-ring and seal kits are so expensive and sometimes hard to source, but many companies make orings and seals that are unique and cannot be found aftermarket,
If you are lucky you may find some but the only way of doing so would be to take the actual seal and orings down to your local bearing and seal supplier and they will measure it up and do their best to find some for you...

The contacts on the microswitch have probably eroded a bit with age. The simple fix is to remove the red cover and adjust the setscrew that hits the microswitch plunger. Loosen the locknut and use an allen wrench to adjust the set screw. If you aren't sure which to adjust, power up the washer and pull the trigger while watching the motor assy. You'll see an arm moving outward when the trigger is released and in when you pull it. Follow this arm to the adjusting screw. Had the same problem with mine and had to move the screw OUT a half turn.
Hope this helps.
