Not sure if they fixed that issue by '01. Easy way to clean it is to dunk the mechanical part ONLY in MEK to soak and it'll clean out the carbon. DO NOT put the diagphram in the MEK or you will be buying a new one ($80+ last time I checked). Steve They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
