I have a Snapper P21506b that I bought off of Craigslist. It worked quite well for the first few weeks, but has started to have trouble with the blade clutch. At first I'd have to hold it down for a while and walk around waiting for it to engage. Today it wouldn't even engage- I waited about five minutes with no luck. Any recommendations on fixing this? The clutch cable is really loose (do I just have to buy a new one?) but I've used my hand to pull out the slack while holding the lever and it doesn't do any good.
