0David97 9 years ago Putting a capastator in wouldn't increase the power of the engine. If you are doing it because it isn't sparking properley my geuss is that the spark plug isn't clean. Clean it with a wire brush to start off with and then dip the ends (NOT THE POTTERY BIT) in petrol and scrub again. Wait untill dry before putting back in. Be rough, it would be hard to break with a wire brush. Also putting a capastator in would put the timing off.
