i have a regular NT carb on a sd stinger 66 cc engine, with about 25 miles on it. the problem is i have had a very hard time getting the thing to start. and i have to first warm it up with a hair dryer. but last night i figured out what was going on. i had the needle clip on the second from top notch (5 notch needle). and the bike would run good, when i could get it to start. but i decided to put the clip back down on the 3rd notch (where it was when i got it new) i closed the choke almost all the way. AND IT STARTED! so for what ever reason the engine wont start when the clip is on the 2nd notch, but the 3rd notch it will. the only problem, and the reason i put it on thr 2nd notch in the first place, the 3rd notch makes the engine run much too rich. and it will "4 stroke" almost the whole time except wide open throttle. so now its really annoying. i have to put the clip on the 3rd notch, start the engine. then take it apart and put the needle on the 2nd notch after the engine warms up. then i can drive it and have it run pretty good. but it seems very dumb i have to do this. i have tried the "tickle botton" but that seems to only make the thing get flooded and then never wanna start. so im now thinking maybe i should try going with 1 size smaller jet. does anyone think that would help? or does anyone have any other sugguestions... i do have a set of jets i ordered from sick bike parts. i have 60-78 (60-62-64...) ???? whats do you guys think?
