'82 GL1100A, cylinders flood with fuel when off

Postby jmaldo » Sat Dec 19, 2009 12:49 pm



Hi,
I have a 1982 GL1100A Aspencade which I installed a rebuilt kit for the carbs due to bowls leaking. Problem got worse so I took it to the local Honda store mechanic. He rebuilt the carbs again and external leaks stopped. Problem now is that the cylinders are flooding with fuel when bike is not running. He can't figure it out and quite frankly niether can I. He said everything is set correctly in the carbs and needles and sets are new and floats are adjusted correctly. He has over 13yrs of experience and said he has never been beat and can't figure this one out. Anyone have any ideas what would cause this problem and how to fix it?

Thanks
John Maldonado

Are you turning the fuel petcock off when the bike is not running?

Yes, I turn the valve to off and have to run the bike until the bowls are empy and the bike stops running in order to keep the piston cylinders from flooding. Bizarre isn't it!

Well I'd have to say it's floats, then, despite the fact that they're adjusted. Is it all four cylinders, or just one? Let it sit for a while, take each spark plug out one by one, and see if you smell gas. That will help narrow it down.

Ya know, the mechanic never told me if it was all four or not! Hmmm? I like your idea of opening the peacock and letting the cylinders fill then pulling out the spark plugs one at a time. I'll do that and check each piston as you have posted. I agree, that it sounds like a float problem. I'll get back to you on my results! Thanks!

Now we are getting somewhere! I pulled off the tubes that connect the carbs to the heads and opened the petcock. Fuel started leaking out of number three as if it was a leaky faucet. One was completely dry and the other two were just a little damp. When I closed the petcock the leak stopped! I'm pulling off the carbs and checking the float bowl setting and will check the floats to see if they are cracked, filling with fluid and no longer floating like they are suppose too. We are moving forward! YEAH! Thanks for your help wingadmin, it is truely appreciated!

Merry Christmas!

Thats one of the first things any tech checks when you clean a carb or rebuild, no matter if it is on a Bike or what ever.It sure sounds like you have a float problem. Good Luck in fixing that problem.
WA9FWt Phil Happy Holidays too All.

OK! I checked all the floats for leaks then reset the float hieght. Then I put the bowls back on and connected carb to the tank petcock. Only one carb was flooding and fuel was dripping out of the carb down spout that goes to the cylinder. I pulled off the bowl and when I have my finger pushing on the float, fuel stops flowing. I moved the float needle and seat to a different carb and the problem moved to that carb. So...I think I have a defective new needle and seat, does that sound right to you guys?

John, you could install one of your old needle and seat assy's and see if that corrects the problem.Or just ask that friend of yours
to see if he has one laying around. Being all new should not have caused this problem. At least you have found it the way it sounds. Good Luck and a Happy New Year. WA9FWT Phil

Alright! I changed the needle and seat for the float and the leaking problem went away. Now I have another problem...Hard starting, once started it idles ruff until the bike is warmed up. Then it runs wonderfully. Any one have any ideas? I think it could be one of two things; the floats are not adjusted correctly or the choke is not set up correctly. Any feedback is appreciated!

Have you checked the plug gaps or even checked the plugs.I had a plug one time after in warmed up made the engine run a lot better.Do you have a inline plug assy to check ignition and see if the spark is the same on all. I may be way off on this, but doesn't hurt to check.nothing lost but some time. I'm sure others will come up with better idea's.Good Luck.

I'll check the plug gap. I did take the bike to someone else since my last tune up. They did remove the plugs and may have bumped one out of tolerance. Thanks for the input!

John , there could be a lot of things that cause hard starting. Best to get a hold of a manual and start checking.
I could fill this page with all that cause hard starting.Best to get that manual!!.... one thing at a time,and good luck.
It can't be to serious if when it warms up it seems to be fine. Rememeber a honda is cold blooded .Just like a good woman, it takes time to warm them up!!! :roll:

Hard starting problem was that the floats were not properly adjusted. Bought the float adjustment tool and bikes starts right up! Now I have a problem with it knocking or missing when cold. Problem goes away when the bike warms up. Also noticed alot of whitish smoke coming out of the right exhaust pipe. It wasn't like that before we started rebuilding the carbs. Anyone have any thoughts?

Sure sounds like to me one cyclinder is not fireing properly. I would still check those plugs.I just came across this now, and don't know the history of all.but it to me sounds like a plug.

Wow, I've come a long way from leaking carbs to misfires during cold running to where I am now! I warmed up the bike and connected a carb sync pro that I purchased. The carbs were way off, so I adjusted them according the this wonderful website. It worked out great! The bike is running even better than it did when I first bought it. The only thing I have left to do is adjust the pilot screws on each carb, new ones were put in. None of my tools fit in the space below the carbs to adjust the screws. Is there a special tool or some kind of trick I can use to make this adjustment?

Thanks for all the help! This website has been fantastic so far!

Hate to tell you this, but you'll likely have to re-sync the carbs after you adjust the pilot screws. :)

I'm okay with the resynchronize of the carbs. I just have to figure out how to get a screwdriver between the carbs and the motor, then I would be glad to resynchronize

I found this tool to be helpfull with that. I wasn't able to use it on all the carbs but it worked on 3 of them.

I'm having the same knocking noise when it's cold at low RPM. I'm going to check the plug gap and see if I can sync the carbs.

I would also check to make sure that your gas cap is venting. I found mine was not venting at all and the pressure that builds might be pushing past the floats. I read on here that you can drill a "small" hole in the cap or try and clean it out. Use SeaFoam. It works great.
How many times do I have to tell ya,,, The right tool for the right job!

just a note which probably most of you know anyway, but, at least on my 1980 1100, gotta close petcock when not in use. Forgot one winter and couldn't figure out why engine wouldn't turn over in the spring. Oops, gas in tank flowed right thru carbs into cylinders and ultimately crankcase. Pistons had no room to move! One way to give the crankcase and bearing a bath, but not recommended!

That's a sure sign of leaky float valves in the carburetor(s). It's always a good practice to shut the petcock off anyway, but if your carbs are leaky, then it's an absolute necessity.
