    79' GS550 Will run on starter fluid but die after a few seconds

    My bike will run when I spray starter fluid for about a few seconds and then die. Would love some help troubleshooting if anyone has any ideas.

    Here's some info on it:
    • Just resealed the gas tank with por 15.
    • Cleaned the carbs
    • Cleaned the petcock
    • Tested to see if the vacuum worked and gas did indeed come out when I kicked it.
    • Makes a sort of higher pitched noise when I try and give it gas.
    • Might've accidently screwed with the jet positioning when I cleaned it.
    What else should I check to make sure gas is getting to my carbs? Is it possible to clean the fuel line to the carb and where the gas goes immediately after the tube?
    Should I try and retune the carbs and how would I do that?

    1A) (NEW) Trying to diagnose running problems on a bike with an unknown maintenance history. Common maintenance items like clean carbs, properly adjusted valves, no air leaks in the intake system (airbox, carb boots), a clean gas tank (no rust), and a properly functioning petcock are 100% mandatory for the bike to run properly.
