They're not too hard to Fab out of stainless. I made the one on the right for my 3400. The inner is still available for the 3400. I think they're the same as 3700.Pair of bar plates for a Poulan 3700??
We got stuff and long green.
I've got one of them with the shafts swapped over in my Mac Super 44A and another one coming for the 790 I picked up recently. They need the 'low profile' fuel pump/filter/inlet section on the bottom of the carb in order to fit the air box on a lot of saws fyi.The china clone of the Stihl 070/090 carb is cheap on evilbay and with some work (swap throttle & choke shafts) can be made to work.
