I am having trouble with my dad's engine, it starts and idles fine but when you run it slowly up to WOT it will run fine for a couple of seconds and then start to die out. When you quickly try to rev it up it dies. I have checked all my lines to make sure that there are no cracks in them that would lead to leaning out. Does this sound like a low speed setting problem. The engine is an Evolution .40NT. I have adjusted the high speed needle all over the place and it doesn't seem to make a difference in what i described above.
