I have a 1996 Murray mod 46904x92a. It needed a new starter as the old one died. Wouldn't even turn with direct battery connection. Got a new one off ebay. Freewheels fine with battery power. Installed it and it won't barely spin the engine. I have 90psi compression in both cylinders. It spins great with the plugs out. I can start the engine with either plug in, of course running like crap, but I know I'm not locked up or having no spark. This is all with a 225amp booster/charger. I even put the cables directly to the starter terminal and an engine ground. So my questions: possible bum starter? Is there a compression release on these engines that may not be working? Is 90psi a good compression reading? Lastly, the engine isn't real easy to spin by hand by turning the screen on top of the flywheel. Not real hard, or no rough spots, just that you can feel it up against the compression. Is there a torque spec for resistance? Meaning turning the flywheel with a torque wrench to see if its out of spec. I'm guessing I got a bad replacement starter. Thanks for any help!
