Re: Cleaning a Holley
good spray carb cleaner is fine. for that holley, get a new bowl gasket and an inlet screen(most people do not realize that they have one). remove the bowl, spray the hell out of it and the metering block, and reassemble. holleys do not (BIG DO NOT) like dirt of any kind(really messes up the idle circuit and the power valve). you will also want to reset the float when you are done.
