In the biopic "Senna", Ayrton Senna mentions Fullerton as the guy he most enjoyed competing against in his entire racing career. He speaks very highly of him as a person and talks about how much fun it was racing Karts in those days. As he put it, "No politics, no money, just racing".
The side winder came with the air cooled Italian engines in 1964.
Techno is credited with the first kart followed by Birel and Quickkart.
The Zip MK11 was the first English side winder and could have the engine mounted on left or right or dual. These karts were available mid 1964.
My first racing kart was S/H Zip MK11 with air cooled Parilla S13 in juniors in 1965.
For 1966, juniors had to be slowed down and could only use a range of reed and piston port engines, the Spanish Montesa being the Quickest.
Terry Fullerton along with elder brother Mick were front runners in the junior class with there father Mike tuning there engines.
Terry won 3 convective British junior championships with the Zip/Montesa.
He raced Barlotti/Komet and then Birel/Komet to win the 1973 world Champs.
76 was Deavinson/Parilla and 77 Zip/Sirio.
In 1978 Terry was racing DAP/DAP, team mate to Senna.
In 79 he raced a 2 axle bearing version of the DAP with his own company.
In 1982 I raced against him again in South Africa and he was then with PCR engines on a Zip Chassis.
I think he again sold his own branded karts , possibly made by PCRas late as mid 90,s which could have been sold here.
