The engine model is EC37P, and the displacement is 372, not 327 (typo). The kids have pulled off the flywheel, and are looking to get the pictured pulled off to gain access to the block bolts (speculation). The goal at this point is to open up the block to clean out the reservoir and piston parts (dirt and grime). A secondary goal was to inspect the contact points due to no spark being generated--they were thinking that the rust might have something to do with it. Has anyone ever pulled one of these apart? Thanks for the help! Like my letter says, this is off of an all-original Polaris Star Car--and there isn't too much out there about them. Even a specs sheet or links to replacement parts (gaskets, rings, etc) would be appreciated.
