Need info sheet and directions on rebuilding the carb on a Craftsman wheeled weedtrimmer. The unit has a Tecumseh 185 displacement engine with a Craftsman engine # 143.995002. It is leaking gasoline around the top of the fuel bowl due to a defective gasket. I purchased the rebuild kit for this carb, part # 632760. Just need some info on installing new kit. Engine will start and run on starting fluid for a few seconds. Thanks.
