Hi everyone! I just rebuilt a 1998 GTX RFI engine that had blown a crank rod bearing. I am a hobbyist at best so looking for some information on why it might not be starting now that I have the engine back in the ski. Both cylinders test between 140-150psi for compression. Both spark plugs have spark. When I crank the engine over, it will crank for a few seconds, sound like it may try to fire, then it stops cranking. Any thoughts?
