Not Firing

My mini is currently not starting. i have replaced dizzy cap, rotor arm, condenser, points and plugs. i have checked and set the timing correctly. checked the fuel pump all is well. its sparking at the plugs and has fuel but it still doesnt even fire a little bit when im cranking it. when the car was first started breaking it seemed as though the condenser was going. well something was slowly deteriorating until it was undrivable and then just didnt start at all. anyone got any ideas what to check next? as i am stuck thanks guy

Blocked carb? Check your float bowl

Try doing a compression test as the head gasket might be knackered.

Ahh cheers i have checked the float and all seems well but i will do a compression test, thanks for the help shall post how things go
