Posted - Aug 29 2009 : 3:46:06 PM I think the timing resistors should be 10 times their value so that a 100nF 5% film timing capacitor can be used. I agree that a supply bypass capacitor should be added.

The 555 in that mode is prone to variation with changes in the supply rail. Try fitting a 100 microfarad capacitor across the supply pins.
