:The C2 is the same as C1, except for the induction system piping. When a Marvel Schebler MA4-5 carburetor is used on the 6A-350-C1 engine for improved acceleration the takeoff and max. continuous rating are 215 hp (160 kW) at 2,800 rpm.https://www.easa.europa.eu/en/document-library/type-certificates/engine-cs-e/easae088-franklin-6a-350-series-engineshttps://drs.faa.gov/browse/excelExternalWindow/E4BE5ADABA76F70186257BA60052D994.0001
