jim,
It appears Mr. Clooney and John T. are busy (everyone deserves a break now and then!), so I can answer your specific questions and they can chime in when they are available.

The vent you refer to is the bowl vent. It's purpose is to keep air pressure balanced between the fuel in the bowl and the venturi pressure. If the vent system is plugged, it results in additional fuel flowing into the fuel bowl during operation.

If you remove the bowl and turn the carb upside down, the bowl vent is the hole about 3/8" dia, which has a hole drilled into the side of it near its bottom. It vents through the (#24 drill) passage in the right side of the carb when you look in the choke end. These passages associated with the vent system must not be plugged. Be sure they are clean, and remove the largest brass plug on the top of the carb - that will allow you access to clean part of the passage system. It is not so much of a problem on the DLTX18 as it is on the new carbs (DLTX67-73), which use two brass vents with holes in them to fill the 3/8 hole. The restriction is there to improve operation on rough ground, and they plug up easier than the old system on the 18.

Your float level is important, and the fuel level should be 5/8-3/4" from the top of the fuel bowl. The easiest way to check this is to purchase a hose barb with a 1/8" thread and some clear tubing to slip over the barb. Remove the bowl drain and install the barb. Hold the tubing alongside the bowl, and let fuel flow into the bowl. This will show you the true level of fuel in the bowl - you can adjust the fuel level by (carefully) bending the float arm.

Hope this helps in the interim.
