I recently purchased a 1969 Mcculloch 4hp from a friend. I took apart the lower unit and its filled with grease and not oil. It was leaking into the lower unit and I am reeplacing the gasket. Is grease normally supposed to be in it or should I clean it out and replace with an OIL? If so what brand or type? Ill snap a picture or two when I get back out to the shop later today. Thank you for any help.
