I have just been given an ST1 # 37 28 ST1A 28-15. I know the first numbers should be the year of build but have no idea as to how to convert them into English!
It had been sitting for years in a shed and the starting handle had been lost. I took the handle from my ST2 welding plant, switched the pawl for the anti clockwise
rotation, wound it round a few times to get some oil through the system and released the decompressor and off it went. Straight up to speed (1500 rpm) and
steady as a rock. Initially there was no current coming out but having cleaned all the brushes and slip rings, reconnected a wire that was adrift and restarted it
perfoms admirably producing either 240 or 120 at the flick of a switch. Don't you just love 'em? I split the generator from the engine to clean and paint it all and saw
a large arrow on the flywheel indicating rotation...... the wrong way !!!! Maybe that is why I got it
