Now that i have my sled running i need to tune my carbs. Its got about a good hours use on it but nothing over 20 mph. Heres how it runs. It starts up alright, need to prime it like 10 times. (i started it today, used 6 primes, started but had to prime it when it sounded like it was dying). It w idled well but a little high once it was started, around 2500-3000 according to my tach. So i let it warm up for 5-10 mins and rode around. I came to a stop to check the idle and it went down, around 2000. So i ran around some more and came to a stop, it wouldnt idle withought dying. when i first started it it smoked a little, then the more i ran it the more the smoke went away, when i was done riding there was hardly any smoke coming out. I havent checked the plugs yet. Where do i start with the carbs? I htink the air screw is out about 3 turns. I remember when it went to low idle (when it was about to die) i woud hit the gas and it would bog for a second then catch back up. what should i do with the carbs? Increase my idle screws, turn my air screws in?...
