How is the piston oiled?

[DrDaveBilliards]

@TheLionRichard

Oil is splashed around in the crank case to lubricate everything.

For more info, do a Google search for "lubrication in small engine"

Are those the only parts in a 4 stroke engine??

thanks in advance :)

@Greengun420

Obviously, in a modern and larger engine, there are more "details" to make everything work efficiently, but the 4 strokes are the same.

Very good job guys! The best explanation I've seen so far.

@surendarbaby

An electric starter motor (or pull cord with lawn mower) is used to get the cycle started.
