This doesnt make any sense to me....i ordered jets for my 14mm bing becuase i need to rejet.(e50 all stock) i have a hi flow airfilter and im getting a pipe....i got some of the jets delivered so i thought id take the carb apart and check everything out. This is my first moped and first time really doing everything by myself with an engine....Now bare with me here.....I took the bowl off and then unscrewed the middle part where the jet goes....i was confused because this metal part is about an inch long and the jets are so tiny and it didnt look like anything fit....but i soon realized the jet screws right into the metal part, and i didnt have a jet in there what so ever. Im stumped because my bike was running fine before this with no jet....i actually thought it was running lean becuase i put the hi flow airfilter on it and the motor was runnning hot and reving very high. How could this be if there was no jet? putting the jet in there makes the hole so much smaller for the gas to go thru....if i had no jet i shouldve have been super super rich or not even started right? or just bogging out? please comment or help thanks.
