  • Sounds like a vacuum leak.. the opposite of a bad gasket and one of the biggest pains in the ass to fix. You need a vacuum gauge, a schematic of the vacuum system to the carb (87, I'm guessing it is carbureted), and labelable tape like masking tape so you can label disconnected hoses and their respective ports. Hopefully someone else will prove me wrong. I rebuilt a carb on an 87 Honda and it had so much vacuum hose it was silly. I still have nightmares.
