2.25 petrol tapping on first start up - Adjusting rocker clearance - 39 Land Rover Series 3 Project

In this video I fill the coolant, bleed the brakes and clutch, fit the inlet tract and start the newly rebuilt 2.25 petrol engine for the first time. It turns out the rocker clearances are a fraction wide, so I adjust those down to 10 thou and the engine runs absolutely sweet.
