Hello, I'm new to smokstak. Just got an old self propelled Rotohoe model 300H, serial # 4095 with a Lauson TLH737WT engine, serial #6005405. Wondering the year of manufacture for either tiller or engine. Has good compression, so if I can find some ignition points, I'm sure she'll run. Just has the coil & the plate it mounts on, no points at all. Not sure if the points mount to another plate or directly to main plate. Looks like there would be another small plate for the points, by the spacing of mounting holes on the main plate. Aim to restore this unit when time allows. It's been implied this may be for lawn reconditioning rather than garden tilling. I've never seen one, so have no idea. It has straight blades about 1 1/4" apart, staggered around shaft. Seems more for garden to me. Anyone out there with any info? Thanks in advance.
