HJM Kit Bike put a 3.5 Briggs from an old Toro snowblower at first. Mounted a new 5hp Briggs in 1977.
Plan to rework this winter. Still have original mirrors, tank, horn. Will be redoing foot pegs. Was Blue when bought painted it when I put the 5 horse on. Thanks for the info on this site! Will keep you posted as progress occurs.
