I took out the carb assembly from my 97' Standard and cleaned out everthing in the vac chambers, fuel bowl float chambers and jets, air funnels and replaced vac hoses that were 12 years old. Got the assembly back on the bike and attached an external I.V. type gas supply. Opened the gas supply valve and gas filled up 4 of the 6 intake tubes and I had gas flowing out of the two ends of the air supply tubes. What did I miss or do wrong in the reassembly process? This is a non-California bike.

something going on with your needle valves in teh float bowls, they should shut off teh fuel when teh bowl fills, you will need to fix that.
Before you crank teh bike over pull all the plugs and then spin it over to make sure that there is no fuel in teh cylinders that will hydraulically lock the piston from coming up and tear out your starter

I thought the same thing you did and pulled the float chambers again to double check everything. Did not see anything out of whack. Did not have a chance to run gas thru the assembly to determine if I still have the same problem. Going to give it another try tomorrow but not putting back on bike until I solve this gas flow problem. I might push gas thru each carb gas drain tube at the float chamber to see if I can get the needle valves to seat before running gas thru the gas line. Just brain storming. I have done a lot of carb work on older Hondas and have never had this problem before. The mechanics are similar from carb to carb on Hondas no matter what year.

you should be able to take a small container and supply gas to each carb via the normal inlet and it should shut off when teh bowl is full.

How fast did it fill? If it was a very slow drip, it's probably a failed needle valve seat, and there isn't much you can do about it other than replace the carb. If it was a fast fill, you likely have something installed wrong. Possibly a bent tang on the float. Neither of those would be very visible.

Is it possible that the gas line is misconnected to perhaps the vent lines?

I had to replace my needles about two years ago. Problem solved. I was told that the very tip of the needles that shut off the fuel are a man made material that can fail. I've never heard that discussed on the board before and can not verify for sure. All fuel in my area has corn in it so that may be a factor also.

If you did not disturb the float/needle assemblies then I would suggest looking elsewhere for the problem.
Possible the gasoline supply you used was high enough to create pressure that could defeat the floats ability to stop the flow. Might be some crap in the gasoline preventing the needles from doing their job.
If you did a detail dis-assembly however there can be many reasons for the failures. You may not think that parts of a carburetor wear in but I will say they do. Trying to put the items back exactly as they were is an impossibility. There also may be the possibility of mixing parts and/or damaging parts.

I currently have the carb assembly on the bench after revisiting the float bowl chambers. I hooked up an external fuel source and everything seems to be fine at this stage. I checked each bowl to see if there was actually gas in them by draining each bowl seperatley to see if there was gas. Everything normal. I did not find anything worn, broken or bent with the float chambers but who knows what I did when I took them babies out to clean. Maybe I just did not have them mounted right and seated. I will let you know what the outcome is once I get the carbs back on the bike. Like all of you, I have never had this happen to any other Honda carb I have worked on in the past. Thanks everyone for your help. I hope I will not be calling on you again for the same problem.

Got the carbs back on the bike. Did not have gas running into the intakes this time but I am back to my original problem and the reason for pulling the carbs. Bike starts fine with choke. Take choke off, bike stalls out. Leave choke on, bike stalls out if you gently twist throttle but will, if you quickly twist, the engine revs up like it supposed to. According to everything I have read on this site it sounds like slow jets. I thought by taking those out and soaking in carb cleaner would solve that problem. I also use a very small wire used to clean paint sprayer nozzels to clean out the small pin holes in both the slow and main jets. The only thing I did not do was pull the pilot screws out to check their condition. Should I go with replacing just the jets or should I consider a total rebuild considering the age of the bike? If a total rebuild, does anyone have suggestions as to where I can find a good, reliable rebuild person or place to ship carbs for rebuild?
