hi my gsx550 needs help i have taken the carbs off because it fails to start it has black plugs on the right very clean plugs on the left the float height on the right is as spec 20.5mm and on the left were the plugs are clean (to clean )the height is 17mm so is thiswhy the bike dont start so why black plugs on the right when the float height is right cheers andy

Left side plugs are fuel washed (i.e. flooding) leaking needle & seat in the carb will do this, I guess you park it on the sidestand. Fix the float levels, and give them a good clean whilst you are in there, should help.

so is the float height causing the washing and setting the height cure this andy

[Dink]

No the float height needs to be correct regardless, the washing is fuel seeping past the needle and seat, which is why I suggest a good cleaning whilst "in there".
It wont hurt to test your fuel valve and see if it is leaking as well.

so if the needle valve is letting fuel by does it need replacing or is it just dirty cheers andy

[Dink]

May need replacement, clean the carbs out first, then see if it continues, if it does replace them.

Grab yourself some new rubber from Robert Barr. It's worth the $12 to be sure, no?

Honestly it could be either or both. BTW I second getting an o-ring kit from Robert Barr.
