Hi i just bought a tnx 5.2r and it has a FR-32FX .32 engine in it. My problem is, when i turn the motor over with the rotor starter, the piston inside the engine sounds like it is hitting something, like making a 'dinging' sound. Is this normal because the motor is new and is tight and hasnt expanded? I'm using just the standard glowplug that the engine came with.

Thanks.
