Need your Help - Mazda 13b motor in a Manx

Hello all,

I need your help I have a Mazda 13b motor in a Manx. I think the motor is a 1985 but not sure is there any way of telling what year it is.

Now the reason I ask is, it's been running really poor and I thought it needed a tune up so I did that and still running bad so I asked on RX7 site and they said it's a carb. problem so I over hauled the carb. WELL GUESS what it still runs bad.

So I did a compression test and the front rotor has 0 yes zero pressure. So I think I need to rebuild it.

Any help would be great

Thanks in advance.
Greg
