If my 98 blaster doesn't idle and runs a bit rich could adjusting THe airscrew help? It probably needs rejected but thought I'd ask.
 
Ok the main should be around 290, when u have the carb out check the slide is opening closing properly then u can adjust the air screw accordingly
 
adjusting the airscrew/pilot jet circut.....

this shouldn't be a one time deal, i adjust my airscrew daily for temp changes, and sometimes even during the ride, especially during this time and springtime as daily temps may easily fluctuate 30-40 degrees.
i always jet the main rich to cover these,
as long as it's not fouling plugs.
