Gill and Barnicoat shared the front row of the grid for the final with Jones, who grabbed second from Barnicoat in heat two, set to start third. However there was heartbreak for Jones when his kart refused to start, leaving him stranded on the dummy grid.
Gill tried in vain to keep Barnicoat behind him at the start but Barnicoat was too strong on the first run down the Dragon Straight and slowly Gill began to fade leaving Graham as Barnicoat's nearest challenger. For lap after lap the two leaders traded fastest lap with Barnicoat barely maintaining a five kart length lead over Graham.
In the final three laps Barnicoat finally broke Graham's challenge and took the chequered flag by nine tenths of a second, inheriting the championship lead from the absent Xavier Warburton in the process.
Graham admitted that Barnicoat hadn't put a wheel wrong all race and wasn't too disappointed with second while Phibbs finished third but was more than five seconds behind the top two. Hamilton and Robertson completed the top five with Gill only eighth.
