I cant get the wheel off my mobility scooter
Mine has 1 nut and I just rang an engineer and they told me for mine (mercury m48) it should definately come off once the 1 nut is removed and if it doesnt its ageing and rust. He said what he does is turns the scooter on its side, turns the wheel hammering it until it breaks free of the rust

I have an older shoprider mobility scooter. The
The two spot painted screws on the side of the throttle are indeed allen key grub screws. These need to be loosened but not taken all the way out as they are very small and easy to lose! I would advise removing as much of the paint as you can prior to loosening these grub screws. Also, be VERY careful not to round off the heads in these screws as its very easily done. When these have been loosened, you can slide the throttle lever downward and off the throttle pot shaft. The flat headed 'screw' you can see is not actually a screw but the bottom of the throttle pot shaft. This will only turn about 45 degrees in each direction and is not meant to be unscrewed. It is for adjusting the throttle back to neautral when the lever is re-fitted. You should be able to take the throttle assembly out from the top inside the plastic housing. Sometimes the three wires that connect the throttle pot are soldered into the wiring loom and sometimes its a plug that connects them. If its a plug, just dis-connect it to remove the throttle pot. If its soldered, I would leave it conected. When the throttle pot is removed, there should be a nut on a threaded part of the throttle pot. Remove it and slide the spring off. Fit a new spring and do the reverse of what I've told you to refit the throttle pot. When fitted, it needs to be set into neautral. You do this by turning the flat 'screw' on the bottom of the throttle pot shaft. It needs to point front to back and is VERY sensative. It should be done with a multimeter and may be best left to your local dealer but it can be done without a meter with a bit of patiance. Make sure the rear wheels are off the ground and just turn the screw very slightly in one direction untill the wheels move. Then turn the screw in the opposite direction untill the wheels stop or start turning in the opposite direction. The key is to find the middle of this setting where the brake has clicked on and the wheels are not rotating in either direction. When you've done this, lock the grub screws on either side of the throttle and you're done! PLEASE make sure you cannot push the scooter manually when the key is switched on as this would mean you're not quite in neutral and the brake is not working, meaning you will not stop very quickly or even not at all! Hope that helps...
