Hello me once again, Im having a heck of a time getting my 76 gold wing going. Checked electronics all check out ok. Checked fuel pump good supply of fuel. Try to start bike it wont run. took false tank and air box off sprayed starting fluid into intake fires right up until i stop spraying fluid into carbs. I was wondering if there is an accelerator pump on this year bike, if not could someone please explain to me how the fuel is to be delivered to each carb? New bike to me cant wait to ride it.

You have applied the choke to no avail ???

If so, try a sharp rap with the plastic end of a screwdriver to each float bowl, may have floats hung up. Not familiar enough with this particular carb, but most of the time there's a float bowl drain screw, remove and see if gas comes out.

If neither remedy works, may require a carb overhaul, if you're not familiar, at least get a manual.

Yes i have tried the choke in all different positions and gas in flowing from the bowl drains. Considered doing an overhaul but not sure if i could conquer that or not. Thanks for the reply Tony.

If you have fuel to the float bowls and can't get it to fire, sounds like the jets are plugged.

Has the bike not been ridden for a while ???

Gas can "Varnish" (actually Polymerize) after it sits too long.

Sounds to me like a thorough cleaning of the carbs is in order in your case.

Ok tony i will try that. Do i have to take the carbs completely apart to do that? and what type of cleaner do you recommend?

Go to randakks.com He's a GL1000 specialist and sells overhaul kits. Your carb passages are definitely clogged, thus not sucking up fuel. You could try the 'in situ' method of pulling the fuel line off the carb plenum (the main housing for all four) and pouring in carb cleaner like the Yamaha cleaner or Seafoam. It's also on randakks.com tech page. These carbs have very small tolerances for fuel passage, and must be clean. Also try spraying carb cleaner in the pilot screw passages. Carefully remove the idle screws (not the carb sync screws!) from each carb (don't lose the little spring or washer) and spray them out. Did you check your air filter too? Try running the bike with no  filter in. I will almost bet it's carbs.

The correct way is to disassemble the carbs, soak the bodies and all metal parts in carb cleaner and reassemble after ensuring all passages are clear and all parts are serviceable.

mag recommends a good source of parts and information.

At the shop in '86 we recieved a bunch of 2 year old Yamahas, all required "carb jobs" as they had sat ina warehouse for quite some time. We used the "squirt carb cleaner into the float bowl" method, worked on ~75% of them.

To do this, remove the fuel inlet line and attach a squeeze bottle of carb cleaner, Yamaha makes a good one, and fill the bowls with cleaner, wait 24 hours then empty the bowls, try to start, see what happens. If it doesn't work, all you've lost is a day and about 10.00 for the cleaner.

Well i hope i have found the problem took the complete assembly apart including carbs. the carbs and all of the jets are very clean. But the fuel rails inside the manifold seem to be plugged up i tried blowing air through them only got a wisp of air. seems to me that if they have to carry fuel to four carbs they should be alot less restricted than what they are. Went to the parts store got a gallon of carb and parts cleaner they are in the soak now for the rest of the night .I will blow compressed air through them tomarrow and hope that does the trick. Then comes the big challenge of putting the puzzle back together again. lol. thanks for the help hope to be on the wing in the wind soon ........ Pork:clapper:

Even if you decide not to completely disassemble the carbs at least remove the float bowls, remove the pilot and main jets, shoot carb cleaner thru them and blow them out with compressed air. Probably a good time to check the float levels. I'm not sure I'd recommend a complete overhaul unless you are VERY comfortable with these carbs. I probably rebuilt 50-60 single carbs, and probably 30 sets of four carb banks off jap bikes before I ever played with a GL. You can SOMETIMES get away without doing the complete and thorough separation of the whole works and rebuild of each carb. Many times if it's someone elses bike and they're broke$$ I'll just clean the jets, set the floats, and pull the slides to make sure the needles and needle jets are ok. Works 90% of the time. Bob
