Currently working on a Briggs which is on a early 60's Porter Cable Surburan. I beleive it to be the original 6hp to the tractor. I can not locate any model numbers on the shroud. The governor is also different then I am use to seeing, more like a cheapo vertical shaft briggs. The coil is also different with 4 mounting holes as compaired to 2. I have no spark, I would like to try a new condensor, then coil once I figure out the model.
