Due to a previuos owner the float bowl screws on my NC23 are a little massed up and since i have orders a new seal kit from Blair @ litetek i thought i would replace the screws with new allen bolts.

Does anyone know the correct size?? CMSL showes the size as 4x16 so does that mean i need M4 x 16mm.

Thanks

M4 = 4mm dia, uses 3mm allen key
