Part-1: 3hp Briggs and Stratton engine overhaul (for mini dirt bike)

A teardown of this 3hp Briggs. You get a good look at just about every part of the engine in this series. Including the solution to all sorts of problems. I may not fix everything first time but the video will always have a solution to the problem!
I'm going to build a mini dirt bike to hoon around on private roads at my work. I work as a greenkeeper and making the dirt bike out of a lawnmower engine is a bit ironic I think! The engine was only £8.25 off eBay so it was definitely a bargain. This video is Part 1 of ??? Parts hopefully finishing with a functional (+Fast?) engine to power my mini dirt bike. Of course I will be uploading videos of the mini bike build too.

Enjoy, and leave a comment on the engine or what I can do to fix it etc. etc.

And if you want to learn about lawnmower engines then 'davidsfarm' has lots of great videos too.

Dave, that air filter is an oil bath air filter. The bottom of it is supposed to have oil in it. The inner mesh part is missing.

that is a 1950`s briggs and stratton i can tell by the carb and the gas tank. i have a link to a video of the same exact engine in running order if you would like to see it.
