stuck float again- hitachi 33's officially suck donkey nutz

I have pulled these carbs off twice- replaced every rubber bit- sanded the vacume passages, stuck various needles and wires through every hole including the bowl passages- i've replaced 2 pilot jets- i spent two entire evenings setting the float levels... i had them all withing 1mm under. i put the rack back together on a level surface with wood on 3 sides. i even polished them with jewelers rogue and got comments about how the carbs look like the best part of the bike.
everything is awesome, she starts first push and runs like a banshee

i go for a 400 mile trip this weekend and 10 miles from home, im leaking gas out of the third & fourth carb drain. it's one of those stupid square floats i know it- they should have angle cut them or machined a surface that wasn't so proned to a rectangular object sticking against its surface. im ready to go get a twelve gauge buck shot, take the gas tank off, and go boom boom boom boom. before i do that, or more likely just go buy a new honda sabre, someone tell me what i can do besides bend the tangs- because if i have to take those bleeping carbs off again, it had better be the last time for a high 4 digit mileage

can i put a different rack on there? if i swap the rack are the mikunis that much better? ive seen different style floats that look angled- if i just take aan exacto knife to them maybe?

 

Had the same problem with my X. Drove me nuts. Mine was float tangs, but not the ones that the needles sit on; rather, it was the tangs that determine how low the floats sit when the bowls are empty. (They rest against the float pillar.) Mine were sitting so low that they pulled the needles off vertical, and the needles stuck.

I know these are Hitachis, but take a look at page 18 of my Cleaning Your Mikuni Carb file and you should get an idea of what I'm referring to.

 

Do you have fuel filters installed? A little trash will make the carbs overflow.
Install or change the fuel filter. Draining and filling the bowls will help flush out the crud stuck in the needle valves.

 

i'll take the bottom end off of 3 & 4 tonight and see what happened
i have a fuel filter installed- recently too...

i'm wondering if anybody replaced or modified those floats because of the tendency to stick to the bowl when full... im thinking maybe shave off the bottom into a different shape

 

Something doesn't sound right -- the floats shouldn't be touching the bowl at all, hence they shouldn't "stick to the bowl when full".

Any chance you could get a pic of the carb(s) in question when you pull the bowl off?

 

ill be sure and take pics

 

never pulled the bowl- drained it , started her up, no leak. rode around town for half an hour, no leak. i'm starting to think that pothole i hit in the freeway yesterday going 80 did something temporary... on the way home last night for a solid 10-15 minutes it was leaking like a civ.. i tried reasoning with it boxer style, it didn't listen
i filled about half a gallon over what i should have for the mileage

i said about the float sticking because when i was wet setting them a few months ago, the fourth carb stuck and flooded once or twice. when i pulled it apart the float was stuck to the bowl... then, a few weeks later i was sitting at a red light and it was spilling fuel. i gave it a hard punch and it promptly behaved.

those are some clean looking mikuni's you had there.. bead blasted?

 

float levels on these carbs,,,is critical ya gotta do it right,,,,,chacals carb write up is key.....read it no less than 5 times before ya attempt it,,,,and take notes!
