The oil plug on the Briggs & Stratton 5.5 HP quantum engine is usually located at the bottom of the engine near the crankcase. It should be a round metal plug with a hexagonal head and a rubber or metal gasket. You may need to use a box or adjustable wrench to remove the plug. Once the plug is removed, you can add the necessary amount of oil to the engine.

If the petrol tank has enough head for the carburetor, yes.

First, loosen the arm until it is moving freely. Next, open the throttle to full capacity while making a note of which direction the arm moves in when the throttle moves through it. Once the throttle is fully opened, move the governor shaft in the same direction the governor arm traveled. https://www.hunker.com/12359232/how-to-adjust-a-briggs-stratton-governor

The fuel flow solenoid or needle valve it controls may be bad/need adjusted/need cleaning. If your engine has one, it is on the bottom of the fuel bowl on the carburetor. It will have a wire running to it, and when you turn on the key, it will make a tiny "click". If you take it off and remove the fuel bowl. and clean it, then put it back on, it may solve your problem.

I am not aware of a method to do that. There are springs and valve guides etc that cannot be accessed without taking the upper engine apart.

I had a similar problem with my generator which also has a B/S engine. Found this on you tube which worked very well for me. Hope it does for you. It also cleans the carb at the same time. Feul lines too if you squirt it in the feul filter and hoses. https://www.youtube.com/watch?v=5AKKuuXUM6I Aloha, ukeboy57

A safe setting for both intake and exhaust would be .004. This is the setting that will give you the best performance. Good Luck Friend.

You could check for continuity with an ohm meter, but I don't know what the resistance of a good coil is. BTW. coils almost never go bad.

recharge the battery pull the plug and see if there is any oil in the cylinder fix the oil leaks OR get a new motor 20 hp from e-bay for a good price that just bolts straight in that way you will have a trouble free mower for the price of a new engine remember you got it free and that means that is is not a good proposition to repair

.040 will work.
