I bought my son a used Kazuma 50 (KZM139FMB). the guy said it was a 2 stroke motor and needed oil mixed. Everything i see online says these are a four stroke motor. how do i tell the difference? If it is a 2 stroke motor what is the proper oil to gas ratio? Thanks for the help.

Use 50:1. BUT MAKE SURE IT'S A TWO-STROKE!
