Andy Young's 1972? Class 1 - "The Heinz 57" 

 

Date of manufacture - unknown, assumed to be between 1970 and 74

Model name - unknown

Restored and owned by Andy Young

 

This kart has been around for some time now, the kart was improved from the original restoration by fitting a 25mm axle and better brake and components, it was raced for three seasons and while enjoyable to drive it was not the most competitive chassis. Dimensionally it is like a late 1960's kart so when my 1974 Barracude chassis arrived I decided it was time to retire the Heinz 57 from racing and restore it again but in Vintage trim for Demonstrations and trackdays.

Modifications - Aluminium floor was replaced with new of same gauge, but this may not have been original in the first place. Leather steering wheel bush replaced with a home made nylon unit. The nerf bars are as I got the kart but do not look original. The bumpers were originally painted silver not chrome. A small bracket was welded on the rear bumper to support the exhaust.
