Micah, as a retired small engines instructor I have to tell you that you are forgetting more than your are remembering. Listen to what members are telling you, so that you can retain the info, don't assume that you understand what they are saying before you research it. How did you find this forum? I'll bet you did a google search. Have you thought about doing a google search "BRIGGS AND STRATTON SERVICE MANUALS PDF" I know that you souls find almost every manual you would need by doing it. I know you may think it is much faster to ask one of us to do it for you, but the only thing you will learn that way is how to ask more questions. Doing your own research will allow you to retain more of what you need to know. If you would have really read the manual, you would have found the section on where engine numbers are located. The techs on this forum don't look at manuals, they read them in sections depending on what they are working on. In today's world the search engine on your computer is your first step to solving problems, but far from the last. Most of us who work in the repair business use the computer and repair manuals on a daily basis. Being able to find answers on my own is more rewarding and makes me a better tech, than having to find someone to answer my questions. I have been doing this for over forty years, and yes I still ask questions, but when I do the individuals I ask know that I have tried to find the answer on my own and need help. Finally, you will look much more intelligent if you would check your use of grammar and spell check. You are not on tweeter, where thx is a word.
