1966 Johnny Walker JW4 Mk2 Formula IV
Johnny Walker first began producing racing cars in 1965 with his prototype Walker Type 65, the following year the JW4 Mk2 his first production racing car was released to the market at the 1966 Olympia Racing Car Show. This car Chassis 6010 was originally built to Class 1 formula IV regulations with a 250cc single cylinder engine and later a 500cc Velocette but following the demise of Formula IV in the UK the car was to discover a new life as a hillclimb special in the hands of Ronald and John Shapley.
By the mid-1970's Shapley had developed the car far beyond its origins. Carrying sponsorship by Carburol Oils and fitted with an 1050cc Kawasaki Z1 engine success was to follow within the racing car class that lead to a multi page feature in the pages of Car and Car Conversions. After the chassis eventually succumbed to the abuse of power far beyond that for which it was originally designed a full rebuild was commissioned from JW4 aficionado Rod Pickup in Blackburn that included additional bracing and reinforcement to the JW4 chassis. Over the following years the car passed between several owners and underwent further bodywork changes along the way until the Carburol Special was to eventually return to the ownership of Rod Pickup. Rod stripped down the car for restoration but progress stalled and sadly due to his sudden death in 2014 this rebuild was not be completed and the Carburol Special was sold again to its present owner.
This car has now completed a chassis up rebuild over the last 3 years and is presented in 1966/7 class F4/2 Formula IV specification with all latter period modifications to the chassis retained. The surviving original parts have all been refurbished and used throughout the restoration but where unavailable or lost replacements have been sourced or made accurately to the original factory drawings and tooling. The chassis is presently fitted with a mock 500cc Triumph unit twin to give future owners flexibility in their final choice of championship or alternatively for static display. The car has a fully documented competition, owner and photographic history and has been rebuilt to comply with current MSAUK Regulations. With the right engine it is eligible for historic sprint, hillclimb in the 600cc classes, HSCC Formula Junior (Class G7) and 500 Formula 3 circuit racing offering potential buyers a very affordable entry into historic Motorsport or to enjoy in a private collection.
