I think I know he answer, but not certain. Bought this little sled to fix and sell, hoping to make a small profit. Anyway, I took the secondary apart to clean and the shaft and bushings are full of grease. This is wrong? I was told once no clutches should ever have grease in them. Also any easy explanation on installing the secondary spring? I mean how tight to twist it when putting it together? Just past the first ramp or more? Thanks.
