56Trk is correct. It is a 4 barrel but not a Q-jet. You are measuring float drop. It does not effect driveability. You need to measure the float level if you already havn't. Take the top off & make sure there is no gas in any of the float pontoons. These are the brass floats & are nortorious for leaking gas into the float. Hold it upside down & maesure the float level acording to the direction sheet.
