Yeah the first couple of runs you may go full throttle, but since the engine is going to be rich it should get up and go all that fast though. You can do a search for the Heat cycle method using the search button at the top right hand corner. For the topic just punch in HEAT CYCLE METHOD and some other threads should pop up. But I read and re-read what I typed in and I basically sumed it up to the best of my ability. But for the first set of runs it's 1 to 2 seconds for the full throttle runs. Just make sure the engine reaches 220f or a little high and you will be fine. This is where normal operating temps start at.

Now this is a shortened up summery but still there's everyhting you really need ot know in there. But still the search button is there if you want to use it.
