Good stuff. Tip for cleaning - oven cleaner (specifically non-caustic). It makes short work of most oil and gunk on engines and the engine bay. Way cleaner to work with too. Spray it on, break the grime up with a paint brush and hose it off (if you have a pressure cleaner, even better). Just an observation - if you flip the 'boomerang' mounting bracket over, will it allow your throttle cable to line up a bit better with the linkage? If you can take some stress of the cable alignment it will help with return and smoother operation (might be enough to sort out the sticky throttle you've experienced)
