Review on 🔥 Enhance Ignition Performance with the OEMTOOLS 25069 Adjustable Spark Tester! by Chris Sweeton

Bought to check an outboard engine for spark. Spark plugs are fairly standard size (Champion QL77JC4). The basic process is that you disconnect the wire from the spark plug and attach it to this tool, then attach the tool to the ground and test for sparks by adjusting the gap to the correct range. The part attached to the floor screws into the plastic housing and thus into the adjustable side. The opposite rod, which should enter the spark plug boot, floats freely. It simply snaps into the plastic housing. My problem is that the free floating part doesn't snap into the spark plug boot. He just pushed into the anther and slipped out of it because the diameter of the floating end of the shaft was too small. An adapter would easily solve this problem, but it wasn't supplied and I don't have one. This causes a problem as this rod is free floating and you need to make sure the tool is fixed in such a way that rod #1 doesn't slip out of the tool and #2 stays upright to keep the connector from falling. Remember that you are trying to maintain a predetermined distance as per your service manual, so it must remain constant throughout the testing procedure. After all, it did the job I needed and I don't hate it enough to throw it away. It's in my boat's tool box, but I have to know that it takes a bit of patience and strategy to get it working properly.
