This one won't fit without converting it to a WT-394 by swapping the metering cover with your existing carb.If you replace the carb go with a WT-194
The Wt-426 is also a good choice which is also fully adjustable but within a smaller range making it less "touchy" to tune.
Actually, there isn't anything wrong with the WTE-x that is you likely already have except the limiter caps which can be removed and reset to match your muffler mod.
