I have one of the kits on my Ariens Snowblower with a 7HP Snow King OHV engine, model OHSK70 (it was my guinea pig). Although, I used the lower amperage stator since it's only running one light. Yea, they are a bunch of different model stators that look very similar.
The kit basically is the stator shown above, magnets, glue, sandpaper, alcohol wipe (to clean before gluing), bolts, a template used to mark the magnets locations and instructions.
The magnets I found that have the right gauss (magnetic field) but need to be cut down to size. To do this I use a ceramic tile cutter. They also have to be orientated North/South/North/South so I paint them red & white (remember your old science classes?). They have to be placed at the right spot, for balance and correct voltage output..... or you can actually generate over 24v.
The differences between the "HS" & "H" and the "OH" engines is that the OH engines have less space behind the flywheel. You have to be careful of wire placement so that the wires don't rub the spinning flywheel. I have to cut the magnets differently for the OHH engines. On the HS/H engines, I cut them in half, on OHH they need two cuts, which gets messy in the saw. Also note the picture above...... the shroud backing plate looks to be two pieces. Many OH engines have one piece backing plates and they need to be tweaked so the wires fit.
Why did I create the lighting kit....... back in 2004, my son wanted lights on his Rupp Hustler, but it had a solid state ign HS40 engine. The price of a new stator & flywheel was over $175 and since the HS engines have different tapers on the flywheel, it may not have fit. Since I have an electronics degree, but don't really use it, I figured "hey, why not". It took multiple tries to get it right. Output dims at idle, and brightens at speed, just like the old Tecumseh engines use to do. At the mini-bike reunion, Brandt Hansen (
Vintage Rupp Fun Machine Snowmobile, Minibike, Mini-Cycle Parts) and a few others thought it was a great thing, the kit was born the next year. My mom would be proud, actually using my degree
