Suzuki GP100 carb issue

[killa]

Bit dissapointing...

After putting the bike back together after the cleaning of the tank, i fitted the new inline filter, put the carb back together (after thoroughly cleaning all of it with compressed air and solvents) and i'm having problems starting the bike.

Before the cleaning of the tank, the bike was experiencing problems leaking fuel from the carb bath overflow. This was possibly due to the floats being at an incorrect height.
When re-assembling the carb i looked over the details in the service manual, which explained the floats (with carb turned over) should sit at a height of 23.3mm +/- 1.0 from the gasket face. On inspection they were a little high. Somewhere close to 30mm.
So i carefully bent the tongue in the middle of the two floats, adjusting them so they come down to the recommended height.

I re-assembled the carb and switched on the fuel tap, after a kick or two she wanted to go, but in the end didnt, and decided to leak fuel. This time it's worse than before.
How is this possijavascript:emoticon('')ble if the service manual gives me the height and i set it more or less where the needle valve needs to be? (which is in really good condition by the looks) I know it's not a very accurate measurement but at least it isn't near on 30mm.

As i understand it the fuel will leak out of this overflow if the level becomes to great...does this mean then that the needle valve isn't seated correctly when there is an amount of fuel in there??
I'm kinda stuck now. I only know so much about carbs but don't want to give up.

Thanks

You know when you turn the screw on the bottom of the carb to drain the float bowl? Where the fuel comes out is a little spout. Stick a bit of clear pipe on this and bend it in a U shape and undo the drain screw. The liquid will rise in the tube to the level it is in the float bowl.

Also watch out for air locks, flooding, kinks in hoses etc. I've known people chase complicated and highly specific problems only to find out it was something annoyingly simple

is the float needle seated properly and the seat not pitted ?

Can anyone shed light onto this?
I dont think it's major at all, sorry if my OP is a little confusing.

should of left the float height setting alone then?

Probably why its off spec, and it works better being off spec? Just a thought

You are using fresh petrol I hope? My GP100 wouldn't go with any amount of shit/water in it.

Pepperami the bodger would blow like buggery through the fuel overflow pipe to see if any bogies needed blowing out and to help it settle down?
I`ve done this many times to good effect.... dont ask why it worked for me but it just did, for example after taking the carb to bits a dozen times on that stupid Sachs XTC125 I`m rebuilding, I blew it through and it seems to have settled down at last,I think? maybe? possibly? I hope
It`s GP100 when did they stop making them? you`re bound to have a few problems
