This high - quality dial indicator gauge is a must - have for working on most two - cycle engines. It features an overall travel of 2 inches, allowing for accurate measurements. The aluminum bridge comes with a thumb screw, and it's designed to let you easily remove the head. This feature enables you to conveniently check port heights and set ignition timing. Moreover, it can also be used to determine the Top Dead Center (TDC) and Bottom Dead Center (BDC), as long as the engine stroke length isn't overly long. With this gauge, you can perform precise engine measurements with ease.

Using this dial indicator gauge is easy. First, make sure your two - cycle engine is turned off. Then, attach the aluminum bridge bracket to the engine using the thumb screw. Position the gauge in place for the measurement you want to take, like checking port heights or setting ignition timing. When determining TDC or BDC, just be aware that it works best when the engine stroke length isn't too long. As for maintenance, keep the gauge clean and dry. Avoid exposing it to extreme temperatures or rough handling. After each use, store it in a safe place to ensure its longevity and continued accuracy.
