My datsun cuts out when i go around a corner. It normally restarts again but this is an on going problem. I ve had a mechanic turn it but it still happens Any ideas?

There are two things operating here that can be affected by the force of going around a corner
the first is fuel and that points to low fuel level in the carby, loose carby body screws /bolts, low fuel level in the tank, rusted or broken pickup pipe in the tank where the fuel surge is away from the break allowing air into ( temporary fuel shortage )the carby
the other is electrical
check for loose battery in the holder , loose battery terminals , loose earth wire / faulty wire to the engine, loose coil -it needs a tight mount to earth out through the case), faulty engine mounts straining wires and looms, loose wire on the idle stop solenoid for the carby
basically you have to consider engine or fuel movement when cornering and check all parts that can move in the cornering process.

Is it carby model or injected.
