The most common point for fuel leaks on the Shadows is the float chamber. Over time the needle and seat (housing) wear and don't seal well enough to prevent the chamber overflowing. Repair is just a matter of replacing either or both at a cost of 17 per side. However, depending on mileage he may want to completely overhaul one or both carbs. This will require one or two overhaul kits at a current cost of 83 per side or just fit a simpler 'service kit' at 55 per side. The second most common source of fuel leaks will be the fuel lines or their associated joints & clips.
I always advise Shadow owners to buy "The Shadow Owners' Companion" By Jon J. Waples. It is as invaluable as having the full workshop manual which can be downloaded for free in PDF format from here:

Please note that it is absolutely essential when ordering any components for a Shadow to always take note of or even quote the chassis number of the car. Crewe had a tendency to include little improvements and upgrades to the cars without bothering to inform the owners and earlier components may not fit - or may fit, but not work correctly! On a Shadow 1 it is on a plate attached to the bulkhed/firewall on the passenger side inside the engine compartment and should read "SRH" or "LRH" followed by a number from 1 to 30,000 (probably around the 20,000 mark for a '74 model).

My 1976 Silver Shadow 1 wipers do not switch off.They operate correctly in all settings but when put them into the off setting they stay on. I will take her to my local garage but I am found of working on her myself. All info gratefully accepted.

Are you setting the switch to the correct position? With the flat of the handle vertical the wipers should be off. Turn it one notch anticlockwise and you're selecting intermittent wipers with slow and fast being the two notches clockwise from vertical.
It's just about possible that the switch is slipping in its hole so you aren't actually switching them off.

Hi Jan good to here from you hope you are keeping well. I have checked all the system out switches, fuses, wiring, relay all seem to be working fine. A friend of mine checked the wiper switch with a volt meter all the readings were ok. What I am trying to work out now is the parking switch on the wiper motor. If it is not set right can this cause the motor to run constantly.

Yes, a faulty parking switch will often cause the problem you're experiencing. Fortunately the switch is adjustable so it may just need tweaking. The method and clearances required are in the full workshop manual which can be downloaded in PDF format from here

Hope you & yours are also well and ... May you be in Heaven a full half hour before the devil knows you're dead!

Happy Days found the fault at the end of the the wiper cable on the wiper motor end there is a connection that connects to a plastic slider. The plastic slider makes contact whit the parking switch. The connection piece was strained, Thanks Jan.
