This video is of Brian Bakewell, and his daughter warming up thier Jr Dragster in Edmonton. It's pretty amazing that this motor is based on the Briggs 5 HP. This one has a billet block and heads, and it puts out about 18 HP, and revs to 8500! some can get as high as 26 HP!! Not bad for a lawnmower architecture. :)
Oh, yeah. It also has a Data Recorder. Reset happening at 0:16. Definitely not a 'kids toy!"
