removing carbs

Prime.
One reason for the level to be too high is that the float needle and seat are not sealing. Take it off prime, then with the drain open, tip the tube down to empty it. Then place the tube up for measurement. Watch the fuel rise. Does it come up then slowly go up past the gasket? That would show the quick fill when the float is dropped, then try to shut the flow off. But the Needle and seat leaking as it just keeps slowly rising.

yep, tried to check the levels again, tapped the bowls to losten valve to no avail. everytime i put the tank back on prime, gas would pour out of the face of number 3, and rise too high on number 4..
so, took tham apart to really clean them and set the float levels, and found what really looks like gravy hahaha
got them soaking in pine sol overnight, and will take a stab at them again tommorrow...

All I can Say is :sick: !!!
Get those things Clean!!!
Don't forget to Inspect those manifolds/ Carb holders. I would pull them off.

Maybe you guys have had better luck then I have but using paper car filters, only works a few days for me. I dont know whats going on but after that the fuel wont keep up with the carbs. If you know of a certain brand of paper filter that works Id sure like to hear about it. Ive tried them all with the same results so Ive been using brass ones but they dont stop the rust powder. Ive ven started pushing Harbor Freight magnets down into the bottom of the tank hoping they would attract the rasty powder. Also if you remove the battery case bolts it will give you a little bit more room for removing & installing the carbs

sounds like you really need to clean, and maybe line your tank.

ok, i give up. i have no reference on whether my readings are correct, or if my floats are sticking. got them back together today and my clear tubes were all over the place! i think they just need to be rebuilt, but i have two jobs, and hardly sleep as it is...
is there anyone on the east coast i can send mine to to have them gone over? or buy a rebuilt set, bench synched, to put on my bike? this old thing has been sitting around way too long without being ridden...

ive got one last local guy i can try, then im out of resources. any direction appreciated

Sounds like its all a bit frustrating, sorry it isn't going better for you.
maybe take a couple days away from it and just order some Kits. Then when they come in, maybe you'll feel like tackling it again.
It can be a bit of a learning curve the first go around.
Also the other problem could be that the float itself leaks. Causing it to "Sink" and let the gas flow into the bowls. Either that or worn Float Valves. Did you keep the needle with each seat like they came out, since they would be worn to each other?

yeah, its starting to get to me. i put them back together today. i did put the needles and seats together, numbered on a peice of cardboard, as to which body they went with. he needles did have small grooves in them and #3 was still leaking gas out of the carb body when i primed gas back into them. the float tangs themselves had been bent before, so itried to the best of my ability to straighten them out...im guessing the float valves, on at least the one with gas running out of the face. prob the other one with the gas in the clear tube a full inch above the gasket line as well.(that one may just have air in it that i havent gotten out yet)

having said that, because of my inexperience, i dont wanna order $100 in rebuild kits, and then miss something else.. does anyone offer a rebuilding service for the gpz carbs? just wanna weigh my options..

That 1" above gasket is way high, as you by now Know. If the carbs are still off the bike, how about pulling the bowls, Inverting the Rack or Carbs and posting a picture showing how the Carb Floats are sitting. Kind of a side angle across all 4. Really if everything is working correctly, the floats should all sit very close to the same Height/ angle. If 1 is way different, then there is an issue with the float or Valve. They should be somewhat level with the gasket surface when inverted. This is not exact. but like I said if you are bending the tab, and the float is now sitting at a raised angle, when inverted, something is not correct. While the bowls are off, and the carbs are in their normal upright position, you can run the fuel through the inlet, and operate the float valve with you hand. It shoud shut off with only slight upward pressure. You can take a container and make a test tank, and put the floats in there to see if they all sit at the same flotation level. As to show if 1 is leaking. Or if you have a Gram scale you could weigh them all. Float weight is another point of carburetion that gets neglected.
