ok i think i have figured out the problem!! the high speed needle was broken, instead of breaking the plastic i broke the needle itself so all this time i couldn't figure out why when i turned the high side nothing happened!! i pulled all the plastic out and the top portion of the needle, now all that is left to adjust is the little bolt that is deep down in the needle recess on the side of the carb, i can see it, but i can't figure out a way to adjust it..

today i tried a 15x8 prop at a max of 7200rpm and then a 16x6-10 at around 6000rpm max.. all of this was done by adjusting only the low end, if only i could figure out a way to turn the remaining piece of bolt down in the carb on the high side i think i would have a great engine! regardless, i got the big turd to fly here are some pictures of my first scratch built no plans spad with my first weedie conversion as well.

btw, if anyone can think of a way to turn the high speed needle please let me know asap! thanks!
