you are correct, I had to dig mine out ti find the number. 37536k was the OHH motorsports cam. I have been working on an H50 motorsports and have one of the 36673k as well, but its in the engine.

do you need a Tecumseh hot coil for that 245 cam. this coil will advance your timing. something you kind of need for that 245 cam.
I do have one for sale. if indeed you are running it in a HSSK50 block. (electric ignition)
Also wanted to add that I tried ordering the tecumseh motorsports hs50 cam 36673k from all the online suppliers that show in stock and no one has them......if anyone is interested dyno charged $100 to modify my cam
