hi all, first post here and as lots of 1st time posters do, i come here with a problem. sorry : (

i have fuel and a spark gettting to my etesia briggs quantum powered mower though it will not start. i thought maybe i had sheared the woodruff key so ive taken the fly wheel off and its fine. what i have noticed is that oil is seeping past the piston rings though i am thinking surely this would just make it run rough and not stop it from starting completely...?

any ideas appreciated.

will definitely be back to talk plants later when i have resolved this oily problem!
