hey guys, I have a FIII 600, but the newly rebuilt thing will not start on its on. The only way I can get it to start is by pooring a little gas down the cyclinders. I can see the gas through the lines that go to the carb. Do I have to adjust the screw? The carbs are in sinc and open and close all the same, but the engine just doesnt not get the gas.. any help?

Are the chokes opening when you pull the lever up?

stupid question but you did put on the lines at the bottom of the bowl so the fuel just doesnt run out before you put the carbs back on correct? only reason i ask is ive been there done that.

well I got it started, but only with the choke on. Once it starts I take the choke off and it runs for 30 seconds than dies out. Any suggestions? Also there is a clicking sound, mayb the clutch?

Remove the fuel lines from the carbs. Pull it over and see if fuel is coming out of the lines. If it's just barely dribbling out, there is a problem with the pump, tank, or the required vacuum to get the pump to work correctly.
