yes it is a Continental R6602, its not in a vehicle, its on a engine stand and it runs a well pump that supplys a stock tank. it used to be for irrigation and has sat for a long time. it wouldnt let me upload any pics. the venturi size should be 44mm for this engine. she runs like a top, i would just rather haul gas than propane to the location. here is a link of it running and pumping water.
