True I suppose. If its stuck open. If its stuck closed though there is no way anything can pass through the cylinder.
It would only be the smallest amount that would go through with a stuck open or burnt out valve as there would be no compression or vacuum to draw it through. Only the slight ventury effect from the exhaust system.
It's a miss you hear. No firing. It may backfire under back off like a cam with big overlap causes.
Fuel needs to be forced through a cylinder. It won't just fly through by itself.
