The book is fairly well informative on topics. It confirmed to me that I learned much from watching and helping my Dad as well as realise easier "rules of thumbs" that I could have applied to servicing engines in my personal endeavors. I learned some pointers as well as tips to better the servicing that I do. I give this 5 out of 5 stars for the simply put, to the point and simple to understand reading material.
Clearly written, very well-illustrated book covering basic troubleshooting and repair that isn't covered in owner's manuals. I plan to own this book. I'm guessing I'd save a lot on repair fees for the tillers, mowers, and string trimmers if I had this as a ready reference.
