Hello again, I have a 1984 yammaha phazer Special Edition. The sled has been sitting 2 years and we just took out the carburators and took them to a shop to be cleaned and we put fresh gas in. Now when starting the sled it olny runs on half choke and idles really high (3,500 rpms) and will go if you pin down the throttle at half choke then put it at no choke she will really go, but as soon as you let off it dies. We think its the idle adjustment? Anyone know anything about the old phazers? Whats wrong here?
