My 88 Celebrity engine

With the hood up and you standing to the side watching the engine have someone hold their foot on the brakes firmly and put the engine in gear. If the engine **** or slams into gear it more than likely the very top engine stabilizer mount. If so there is an red ignition running around the air compressor that sometimes starts to wear this wire into which can cause several problems among them the engine can stall at anytime, not start, but it can be a fire hazzard especially if there is fuel or oil present. Hope this helps.
