So I bought a basket case husqvarna 345 and I decided to use it as a learning project. It had a walbro 159a with a stripped low side needle hole and I need to replace the whole carb. Since the 159a is not longer available I'm not sure which carb to use as there are 4 different options. I would like to keep it non EPA so I don't have to deal with the plastic limiters, etc. the only other variable is that I went with the 45mm cylinder kit on it. Should I keep with the stock listed carb? If so, which one? Or since its got the bigger cylinder should I switch to something listed for the 350?
