No need to fear linerless engines. Disassemble the shroud every season and clean the fins. If they are kept clean and oil changed they can last a long time. Like from 79 to 2012 mowing 3 acres on zero turn. The carburator butterfly was so worn that the engine would not idle. Still ran great. Retired due to no parts for the transmission and the blade deck was rusting out.
