Try running some high octane gas. If it's a built engine, then it might have a high compression ratio, causing it to detonate once the ignition is turned off.

you should try retarding the timing because if its to far advanced it will cause excess heat in the cylinder thus allowing the gas to detonate with out spark. A couple degrees will make a difference.
