tengai won't start

[Giampaulo Cinquegrana (John C)]

Hi everyone, I tried starting my Tengai yesterday for the first time. I took apart the carb and cleaned it (fuel was kinda jello-eee). I screwed in one of the pins all the way down and then unscrewed it to see how many turns (like the manual said)... I counted 3 3/4. Try starting her with choke and she would start and then day a few seconds later.... tried again and same thing... tried with choke and throttle and she would start for 5 seconds and then die. Any ideas? I have a second carb from an 89 KLR and it was slightly different: it had no washer (or shim) on the long needle/pin and the bottom pin had a cover on it (the one you turn).... should I try removing the cover? Any help or advice would be greatly appreciated. Thanks, John C. 1990 Tengai 1989 KLR 650
