Help! 2 dead cyl.

you can unscrew the bowl drains with out pulling the carbs.
obviously fuel should run out of all 4 carbs

It likely that i may have overlooked a part of this thread/post, but i still dont know if there is an actual spark at the 1/3 plugs when turning over with ign on... ..

Put new tyres on it, new battery and paint job, wont make the plug fire at the right time....

there is fuel in the bowls

There is fire at both plugs and it seems to be a good strong spark. With the motor running and a screw driver in the plug wire cap the spark will jump at least 3/4" to 1" to ground. service manual shows a 1/4" minimum using a spark plug tester which I don't have. Shorting it to ground and getting a 3/4" spark should be good.

I am thinking that using the aftermarket jets and float valves and also the aftermarket fuel needle may be the problem. I have since learned from Howard Halasz that the aftermarket parts are suspect so since I still have the old parts I am going to clean them in my carb cleaner and put the OEM stuff back in. I also got a Float gauge coming from Randakk's to set the floats with so I know that I am setting them correctly.

it is not uncommon, even for those of us who have rebuilt many carbs, to not get it right the first, second even the 4th or 5th time. Those idle circuits are tiny and hard to clean. I would suggest that you have pretty much eliminated ignition timing and spark so that leaves fuel delivery.

Personally I would pull the carbs once more and make sure the carbs are clean. Soaking in carb cleaner doesn't always do it. You have new jets so I am leaning toward the internal carb body passages. While you have the carbs on the bench squirt carb/brake cleaner through both sets of jets. You should see the carb cleaner come out inside the carb throat somewhere and it should be a good stream.

Good luck.

Throwing this out there. When you put the carbs back together did you by chance close the mix screws on 1 and 3 but the did not open them back up? I always seat them and then back them out to the factory setting. Maybe they are still seated.

no they were backed out 3 turns and since I got it running I have adjusted them on the bike made very little if any difference in the way it ran.........On this note........what kind of tool do you guys have to adjust the carbs....I have one of the motion pro 90 degree tools that they say will work on the Goldwing and it does work but not very well especially on #1 and #2 carbs. I want to get another one that is easier to use if there is something out there.

I did this before I had the Jets back in the carb but not with the jets in......I followed the post in Shop Talk that Roady has posted. It has a diagram in there of where each passage goes. They all seemed clean and the stream came out where he showed it should..... that's not to say I didn't miss something though. I will do this again while the carbs are off and with the jets in place before I take them apart and again after I go through the carbs again.

If you grind part of the collar off the tool it will fit on the carb tower better..take a look while the carbs are off..you'll see what part needs to ground off/down.

+1 on aftermarket jets not being right half the time, +1 on setting the floats again, take a look at eh plugs after running her..plugs wet on 1 and 3?? or dry, black or tan? tells you a lot.

You have the wire that is supposed to go on sparkplug #3 on #1
You have the wire that is supposed to go to #1 on #3

It is wired the way you have it drawn....I just verified it

there is lots of stuff in the way, that is a crowded area!
that makes it allmost impossable to visually verify the plug wires are going to the correct plugs.

It is sooooo eeeasy to just yank the #1 off and stick it on #3 ,
and crank it over

No change??!! If they were right before and you swapped them you should have gotten some backfires.

snip..........

Did it run different? Try running them all the way in and does it run different? It should want to die, if not die, when all the way in. If not the idle circuit is plugged.
