Long sense forgot about pride. But after the time with developing the 660's I'm not quite as willing to do the R&D anymore. Those little aluminum brackets for 372 have changed from when I first used them...to the point they no longer allow full throttle on OEM builds. BUT might be their answer to the wandering idle on 372 style saws if that was where you intended that to go. AND those aluminum brackets work well on the X-torq to OE conversions where you use the XT carb...Also on some of the 372 AM cylinders the intake casting itself is a bit too long and that mouses up the geometry relative to the carburetor as well. Of course a better solution is OEM throttle cable or trigger parts. Especially on the g372xp & xt. Me? I just swapped in an OEM handle on the g372xt.....all kinds of things got better. On the Stihl clones, I did find the carb to carb boot intersection issues as well and rather than fight with the parts just swapped to "used" OEM part by part from the junk pile until the saws ran well. The g366 was the worst / 361 kit as well. SO they got parked. I don't have the time. Some one else's turn.
