There is what I think in magnesion deck and a smaller engine with a red cover on it I just came out of a barn and is dirity it says solid state on the handle part but there is no throttle control it is a small 20 in cut just looking to see if I have something worth keeping or not thanks

If it's a Craftsman try to locate the model number and come back here with it, we can help. All the records in the world can't tell you if its worth keeping. If it runs and meets your needs then keep it. If it doesn't run or does do what you need put it back in the barn
