The Tower .46 carb may be the way to go for a replacement....
....you know Tower will stand behind their parts 100%. [sm=thumbup.gif]
I have 2 Magnum 40-46 carbs NIB in stock, but I'm pretty sure this one
will work....If it doesn't I'll try for a replacement....they need to improve
these things....

The Magnum is .5 mm smaller than the GMS carb, and
being as we are using this as a "Club Racing engine", I'd be at a slight
disadvantage if I changed the carb....
....and if you knew the Guys I fly with, that wouldn't be a good idea. [sm=stupid.gif]
