Anybody know about Aero 80 Carburators?

I was having some problems starting my Aero 80 cold. It will start fine once its warmed up even if it sits for an hour. If you let it sit for a couple of days, you have to crank it for several minutes before it will start to fire and then it slowly fires more and more until it will run on it's own. I had some leaky carb gaskets so I pulled it apart to replace those. In the carb bowl on one side, there is a chamber. On the carb top, there is a pipe that leads to the enrichener circuit that goes down into that chamber when you put the bowl on it. Here is a picture:



There is a small hole in the bowl on the side of the chamber. There is a corresponding hole inside the chamber. I thought that might be to let gas into the chamber to feed the enrichener circuit. The small hole seemed to be plugged and there was no gas in the chamber. I tried to push a small wire through the hole and it would not go through. I then tried my pin vise with a small drill bit. It would not push through either so I tried drilling it to see if I could dislodge whatever was there. When I pulled out the bit, there was metal shavings on the bit. so it seems that I was drilling into the body of the carb bowl. Now I am really confused. If that does not go through then it would seem that the chamber is a blind chamber that I have no idea why it is there. I tried blowing air in it and it does not go anywhere. This chamber would not be in many Honda carbs since there were very few that used this enrichener circuit to cold start. Maybe we have an Honda tech that is familier with this that can let me know if this is supposed to actually go through.

I am no tech but have messed with a few cards and yes that is suppose to fill with gas you might have to do a good cleaning to it to get what ever is blocking the passage to free up I usually use wd 40 with the stick and keep working at it till it's clean or replace the bowel

Hey thanks for the reply, You were right, that feeds gas to the enrichener circuit. I was able to get a small wire through there and then my smallest numbered bit in my pin vice cleaned it up pretty good. I finished cleaning the bowl and got everything back together and now it starts up right away. Even letting it set a couple of days and it still starts right up. Before I would have to crank and crank just to get it to fire once or twice and then crank some more before it would run on its own. Now it fires right up. Makes a big difference if it is working as designed.
