Reply To: Float height adjustment – gt250
If the floats give you drama , go back to factory float, factory float seat well , factory float needle. Start there.
If using new floats , try with their needle seats that came with the gasket kit.
This is because there could be a slight variance of 1mm height difference , the carb needle may have a soft bounce as OEM floats a tad little smaller and more curved , the aftermarket floats would be a little more “boxy shape” with their needles from gasket kit having stronger spring (maybe 2%)
Also the float seats have a HOLE size relative to the needle it is using.
Ie. OEM float seat would say 1.0 , the carb rebuild kit version would probably say 1.5 – Hole size might allow more fuel in easier as long as it is used with it’s supplied needle (the needle may be a little wider to cover the hole) like 0.5mm wider (very marginal!)
Just my thoughts at 10am , so sorry for any grammatical errors , keep us posted!
