Wow , That was awesome & a fast response.

So am I safe to assume this is a matching set.?

*I know this is not the correct section but aprox what are all 3 carbs worth as a set.? Carbs appear to be in good condition & all diaphrams sound good.

Cheers , Jeff

its a set anyway date codes are kinda spread out 301 is late oct and the last one is dec... probably were originally a set though... good luck dan
