RE: Carb for Nelson
I have experimented with the Perry Carb on my Nelsons. A very frustrating experience - despite the excellent service from Gary Conley at Conley Engines. My problem was that the plastic sleeve around the carby spigot keeps coming loose. I think the locking bar distorts the sleeve and loosens it. I've tried different glues without success.
Its frustrating because I've discovered that the Nelson idles very nicely on the Perry Carby and its so easy to practice on your own without a launcher.
