Australiaâs tallest trees can be found in the south-west of Western Australia in the Valley of the Giants. Giant tuart, karri, and rich red jarrah which live for up to 500 years can be found here.
Feeler gauge set. A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts. They consist of a number of small lengths of steel of different thicknesses with measurements marked on each piece.
Use a .010 to .014-inch feeler gauge tool for engine models with breaker point type ignition systems. If the air-gap is too large or too small the ignition armature coil will not receive the proper signal.If the air-gap setting is correct, the ignition armature coil is bad and must be replaced with a new unit.. Disconnect the spark plug wires and remove the spark plug from the engine with a 5/8-inch spark plug socket and ratchet wrench. Dual cylinder model engines have two spark plugs, one located on either side of the air filter. In single cylinder models, the plug is either at the front or rear of the engine.
