Unfortunately I dont see any stickers to indicate its year or model. "J607" It was on an exmark power rake model ra-5000. Best I could find as shown in pic looks like same motor on 1976 5hp briggs.
Can anyone tell me what this spring and hand nut are called. Trying to locate the spring and screw in the picture but dont know what to search for. Tried "governor adjustment screw" but nothing I'm seeing. Might someone be able to point me in the right direction? Maybe a link?
