I built a mini-me for a guy locally, i've put together a few motors now even one for my self, and i have NEVER seen anything like this, it has compression, Spins with slight resistance.

I set the TDC prior to even installing the head onto this motor, Cam is set to TDC, Installed the timing belt, tensioner, water pump etc,

Put the motor into the car today, put oil into the filter prior to install, primed the oil pump and what not, Checked my fuel before installing the fuel lines.

installed sparkplugs, and wires, checked the order twice just for good measure,


When i turn the key over, Fuel pump primes, CEL turns off once its done priming, I turn the key to crank, It starts instantly, but sounds a tad rough, then cuts off and the whole rotating assembly actually kicks backwards about half a turn to a turn. I've NEVER seen this before, I think that i may be too far advanced on my timing, as the only thing that would be possible of kicking the rotating assembly backwards is spark / compression being to early, and when the motor dies out that last spark builds the compression and kicks it backwards,

The fuel injectors are in the correct order, it was the first thing i checked, and from what i can tell the crank is TDC when the cam is TDC, but i can only check TDC on the crank by using a long screw driver, or a clean dipstick into cyl#1.


I've never had an Advanced timing issue so I am kinda ignorant as if this is the result, if so and a few people confirm my theory's then problem solved If not any help / hindsight that you guys may have is all much appreciated.
