Because both valves (or reeds in the case of some 2 stroke motors) in the cylinder head are closed and it is compressing the air and fuel i so the mixture will ignite and cause combustion or firing of the mixture to create power to cycle the motor through the exhaust and into the next compression stroke.
The Champion number is a RJ2YLE. Somewhat hard to find if your not a dealer.
The rocker arm clearance tends to loosen in these engines. This causes too much compression at the wrong time resulting in hard starting. Most people think the battery is weak but a relatively simple adjustment of the valve/rocker arm clearance should solve your problem. Check your manual and YouTube for instructions or consult your local mower shop.
Briggs & Stratton recommends high quality detergent straight 30 weight but this can result in hard starting and may damage the engine at colder (below 40 F) temps. Multi-viscosity standard automotive oils (5w-30, 10w-30, etc.) are acceptable but will result in very high oil consumption at ambient temperatures over 40 F, and may void your warranty. High quality synthetic multi-viscosity oils are best for all temperatures.

The compression of a golf ball is basically a measurement of how hard or soft it is.
Yes, the compression fittings designed for copper work on both soft and hard copper pipes.

Is it hard to kick or no matter how many times you kick it wont start? If the second choice is whats happening my guess is low compression. Maybe a compression test and or valve adjustment is in order if you have good fuel and a clean air filter and good spark. My 2000 ktm 400 would not kick start at all only push start. I had very low compression because of worn rings. If you can push the kick starter with your hand and not using the compression release this is your problem.
there is no hard fast rule here. but typically with the cap off and number one cylinder at TDC on compression stroke. the rotor will point at number one cylinder on the engine.
he worked hard

If this happens to be one of the new plastic cams, Briggs did have problems with them, they had many service updates out on this problem. Most of the Briggs engines do have a 2 year warranty on them, so if this is within the 2 year mark yell warranty. You can also do whats called a disputed warranty, where as a customer can take a engine to a authorized Briggs & Stratton dealer and try for warranty, if the dealer says its not within the warranty period,or they dont feel it is warranty, contact Briggs & Stratton in Milwaukee Wisconsin. If a item on a Briggs engine fails not due to customer abuse, Brigss will pay for it, regardless of age. I once warrantied a crankshaft, which is very hard to do, only the factory can approve a crankshaft warranty, it was 16 years old..but upon inspection, they found they was at fault, and they paid it, no problem. If it is paid as a disputed warranty though, the customer is responsible for the labor charges. Your engine has metal cam lobes. The tappet is hardened so the cam lobe should not wear prematurely. If you have abnormal wear to the cam, it is possible the tappet was not properly hardened. The other possibility is abrasives in the oil, but typically the whole engine would wear out.
