Been on the site for about a year, don't post much, but have learned a lot, like the top says i replaced the joint carburetor(all four), like most FJ works go it was pretty straight forward, figured since i was under the tank i would check my plugs, plug 1 was spaced too far out(about .046 i think) checked the rest and re-gapped to .040 all the way across, getting a lot better throttle response, not sure it its the new joint carbs pieces, or if its the re-gapped plugs, but it was responding like a beast.
ANYHOW that's where i ran into the issue, I'm not sure if i forgot to reattach something, or what, but it dumped all the fuel in the tank(about 14 dollars worth of mid-grade, it was painful) i could definitely use some input, or some local help if anybody is up in the north Syracuse/Oswego area.
any help is much appreciated gents(and ladies) once this fuel dumping issue is fixed i can put her back on the road!!!
Upstate NY weather is keeping me from popping the garage and doing my bidness, maybe ill chance it.
sounds like a problem with the petcock and the carb floats letting the fuel overfill the bowls and piss on the floor. careful as this can lead to fuel inside your crank case or cylinders and result in a bent rod. htm
remove the plugs and spin the engine over to clear it out before you start it.
because you lost all the fuel the petcock is the main problem, floats are secondary.
Mark, naaa, I would rule out the petcock.
It looks like he has a '89 (with fuel pump) so I don't think the fuel got dumped while the bike was sitting with the engine off.
If it's a big gusher, it sounds like a stuck float.... or a small dribble it's a bad float needle o ring.
I hear ya pat , but he dumped all the fuel in the tank so it aint just the floats.
all the fuel dumped after i started the bike running, 3 gallons in about 4 seconds, hope its not the floats, i really did not want to pull the carbs apart, was supposed to have her ready for to get the fork seals done tomorrow, and get it synced up for sea level(i recently returned from co springs, CO) guess that will have to wait, thanks for the input fellas too cold out to really do anything today, so I'm going to pull everything apart tomorrow, guess ill pull the carbs apart and see if everything is lubed up and moving right.
A gusher=stuck float, not so bad, I just did it this morning on my '92. I didn't remove the carbs, just flipped them over, a 2 hour job.
Remove the seat
Remove the side covers
Disconnect the tank fuel line at the fuel pump and plug (quickly)
Unplug the electrical connector for the tank fuel gauge sending unit.
Remove the (2) 10mm tank bolts and washers.
Remove the tank
Remove the (3) 10mm bolts on your air box (top and left and right side)
Remove the 3 Phillips screws for the airbox side cover, remove side cover.
Loosen 4 airbox clamps, and loosen the 4 carb manifold clamps.
Remove the 2 upper bolts on your subframe then push down on your subframe.
Disconnect crankcase breather tube and then remove airbox. If you have Unipods then you don't have to mess with the airbox.
With the air box out of the way, now you have some room to work
Remove the choke cable from the carbs (leave throttle cable and return cable attached)
Disconnect fuel line at the carb inlet and the 4 small choke vent hoses and 2 larger fuel bowl vent hoses
Now straddle your bike and by wiggling up and down on the carbs and remove the bank of carbs from the manifolds.
Put a double folded towel down under the carbs to soak up the gas.
Now flip your carbs over. Watch your cables. You now have access to the float bowls.
Remove float bowls. Do one carb at a time.
Use spray carb cleaner and clean the shaft that the floats pivot on. Spray around and down the float needle.
Gently wiggle the float up and down to make sure it's nice and loose. You will find 1 or 2 floats that are stuck or gummed up.
Reverse for reassembly. Unipods make this job soooo much easier. Fucking with the airbox is a PIA.
Ain't nothing to it, but to do it... Cheers!
not going to lie, this way seems tons easier then the way i did it, i had left the sub frame on, disconnected the box, pushed it back a little, and finagled everything off vertically, it was pretty fast, but still a HUGE pain in my backside. In all honesty though, i thought it was just going to be an easy install and out came that fuel, next thing i know my wife is yelling at me from the window above the garage; and i quote "WTF is that did you just break that thing AGAIN, as god as my witness i will smash it to pieces, and bury you where they will never find your body!!"
So I guess I'll drop my son off at school tomorrow morning, and come right back to the bike, i ain't exactly the happiest dude about not having a job, but i wont lie, this retired at 25 thing is pretty sweet fellas.
yet again, thanks for the info I'll have to remember to snap some clicks while in the process.
posting a little later then i thought, got working on vehicle's and didnt stop. pulled the bike apart, and after i had everything ripped apart i see that almost every other screw is stripped, so now im going to have to go through the process of pulling all these screws out, i just went ahead and pulled them completely off, going to get back to them in a few days not feeling like messing with them, so basically, i'll post in update in 2-3 days :D
So after a day of not being in my garage i go down to get my triangle so that i can measure the new downpipe for my car, and lo and behold my son had knocked my tank off of the table i had it on, and left it there, so it had basicly been sitting on the ground for about a day and a half. super pissed about it, not much i can do i guess, i havent checked it over too much, i can see some fairly heavy scratches, and a new dent or two, guess i shouldn't worry too much about it...lol
You can always have another kid, but you may not find another good tank. React accordingly. :-)

kinda where it gets hairy right there he IS my step son, so he's not really mine, but i DO kind of love him, maybe my level we'll see how much that level diverts when i get a tool to push the dings out, and start sanding. I'm honestly more annoyed that its the original paint job getting messed :p
that sucks man... good luck.
My kids are always messing up my stuff so I hear you... and I have one of those "step sons" too... so I know exactly what you are talking about there.

I cant even begin to count how much of Dads stuff I fucked up. Four boys in our family. So I guess we need to keep this in mind. My 10 year old grandson is coming for a visit soon (my son too). Cant wait but I am getting my shit out of harms way. He loves to work on stuff. My fault, at 5 years old I had him using an 18 volt cordless drill/driver working with scrap wood just keep him busy. Did not really work out for me though. He would bug every 5 minutes for different tool, then paint. Argh you just have to give up your own project. There was an occasional injury but he would go back to work. He made some pretty cool stuff actually.
im with you on that, my little guy, nearly four loves to help work on effie, only trouble i have is he "borrows" my tools or needs the bikes parts for his own job :biggrin: , all good wouldnt want it anyother way,just takes a little longer :biggrin:
wait till the little tykes grow up a bit and try to ride your fj by jamming a stick in the ignition . :scratch_one-s_head:
oh god i may cry if that happens, ANYWAYS, back to the issue at hand.
after i put the joint carburetors on, and got it all back together it started leaking fuel, it wasn't doing that before, so i thought it was a stuck float, but i have a different theory.
if when i put the carbs back on i didn't readjust the intake valves and such, so that the circles aren't flush, would that cause the fuel dumpage?
