Hello. I am working on a 92 kx80. Just rebuilt carb, new gas, plug, 32 to 1 mix. Etc. It only starts when i pour gas in the carb and it only burns the gas i pour in it. It does not seem to draw gas from the tank. When it is running it idles very high. Ive pulled the carb apart twice and im 99.9% sure there is no trash in it. What your thoughts. Could it be not enough vacuum? If so how do i fix it. Also it has good compression at 120.any advise would be great thank you.
