Ok... so the question of Installed weight and fuel consumption has been asked. I'll get to the weight in a minute but have just performed a fuel consumption run at WOT. Here is how it was performed.....
I have re-plummed my stand so the engine will draw the fuel from a graduated container. This container is not "Exact" in terms of scaling but close enough for the purpose. The container was filled to the top, timer started as the engine hit 24oz at WOT. At the 4oz mark, the timer was stopped. As you can see below, the engine consumed 20oz in 87 seconds (actually 87.808 but not slitting hairs here)
20oz divided by 87 sec = 0.229885 oz/sec
0.229885 x 60 sec = 13.7931 oz/min at WOT

There you have it... Actual consumption at WOT 13.79 oz/min
