Briggs & Stratton engine piston

[rocky4]

I have a question. When installing a piston in a B& S engine, is there a certain way the piston must be installed in
reference to the crank shaft. I know some have a mark on top but some do not have any marks. I do see an arrow inside
the piston. Should this arrow be pointing to the fly wheel. Thanks for any help.

Absolutely yes, briggs small engine----does it matter which way you install

Thanks for reply. I do not see an arrow on the face of piston. There is one inside of piston. I did mark piston and rod when I removed them and arrow inside was pointing away from flywheel. Could this have been a mistake from factory?

I did find an arrow on top of piston. It is so light you can hardly see it. All is ok now. Thanks for your help. Great site!!
