According to my Sunny [B310] owners manual, both the A12 & the A15 use a tappet setting of .35mm, or 14 thou. I guess that the A14 is the same.

When the engine is thoroughly hot, remove the plugs & rocker cover. Rotate the crankshaft untill the rockers on number 4 cylinder are "on the rock" That is, with the exhaust valve just closing, & the inlet just opening. Adjust number 1 cylinder. Vice versa also holds true.

The same thing applies with numbers 2 & 3 cylinders. Just rotate the crank in half turn increments & watch the valves. When the valves for nimber two cylinder are on the rock, then adjust number three.

The two end cylinders are linked, & the two center cylinders are linked. Do it this way & you need to turn the crank only two rotations & you will get it right every time.

Removing the plugs just makes it easy to turn.
