Review on 🔧 Innovative Products Of America 7880 6-inch Long 14mm Thread Top Dead Center Indicator, Black by Rusty Heredia

Love it, I work on standby generators and constantly adjust valves in the field. That is God's mission. I know the cylinders are exactly where they need to be for proper adjustment. Screw side turned with changed markings that cannot be erased in 1/8" increments (very important for compression exhaust engines). I just want the tuba the instrument was in to have some sort of lid.
