Hello vivox,
Welcome to the group.
I hope we can be of some assistance as needed but do all of us a favor for which ever machine you a dealing with....
Provide the machine product label information along with the engine label or stamped valve cover numbers on the engine.
We need this information to be able to breakdown exactly what you may need help with.
Just giving the make and model provides very little for us to go on. Some people on this site will not waste their time to help if there is minimal information to work with.
Parts sources that can help you are:
