Can't is a four letter dirty word
I am all thumbs lolData is good. Now to put that back into context, a high performance two stroke should have a BSFC around say .65 or half the number I used earlier for that simple illustration, so it should burn through 32.5 pounds per hour or around .5 pounds per minute. That's more or less 225cc per minute, so it looks like you have more than enough flow under any of those conditions - cap on or off, but get rid of the filter.
Race fuel is much cleaner than street gas and I'm sure you use a clean ratio rite or Accu-Mix jug and a clean filler funnel.
That leaves us electrics and or jetting. I think I covered both of those, but I am more inclined to think that it's a sticky switch or maybe a thumb stuck on a switch perhaps.
