[Michael C Henry]

I'm wondering where to start.Gerald mentions removing carb, screwing nuts back on studs and setting the carb on the studs with a space underneath to view. and rehooking up fuel supply and looking under carb to see if fuel is running.He mentions opening secondaries a little to feed a little air through their idle circuit. I know there is an idle circuit that is sopposed to be taking fuel out of the seconary fuel bowl so it doesn't get stale.I wonder if he ment on a 4160 series without secondary metering plate, no adjustments? He didn't mention dual carbs. and didn't mention any drilling.It worked before.What did I do to screw it up.
