Thanks Dave, every helpful, will get a new vM26 after Christmas rush

I need to replace my old VM26SC carb on my 75 KT250.
The only available option is a new VM26-8074 from the very helpful Mikuni dealer in Townsville.
The problem is that the KT250 original carb uses non standard Mikuni jetting / needles etc and there is no direct jetting conversion to the new carb ...
