I just picked up a Rover Baron 45 with a B&S 3.5hp engine. It only cost $25's and I bought it as a project. Overall it is in good condition.
However it does not appear to have spark, I have another sparky but I think it won't work either. I don't know if it has points or anything.
Hear are the numbers off it.

Model: 92908 Type: 1963 02 Code: 78102302

Any ideas on when it was made etc. I know it is a 148cc as most of the stickers are still intact. The engine itself is yellow in colour, don't know if that helps.
