Too add a bit to this:
Please remember that we are a group of dedicated lawnmower modification "experts"; we are here to talk about our modified lawnmowers, how to make them safe, reliable, fast & fun.
If you're simply here to chat, or to make your mower fast without doing any safety modifications - you will not be welcome on the forum. We preach safety first on this forum, and you can't have safety without spending any money. If you don't want to spend any money, you shouldn't be here. It's as simple as that.
