As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

I put my fresh carbs back onto my bike this evening (dipped and new O rings) and tryed to turn it over for the first time. Well she turned over and started than there was a pop and it died when I went to restart it gas was coming out of the carbs but it did start. No gas apperd to be coming out of the over flow lines.

What should I look at first to try and fix that gas's leaking.

The bike is a 1980 gs750L stock airbox.

Your fuel would be continuously flowing, even with the bike off. Unless your floats and needle valves are working exactly the way they should, fuel will bypass the floats and flood the carbs, much like you're describing.

OK I will have a look at that then. What part of the carbs would the gas leak from in that sanareo?

Thanks for your help and sorry for what might be stopped questions just trying to lurn as much as I can from my mistakes and success.
 
First, I would confirm that your petcock is working correctly. Pull the fuel line from the fuel tee between #2 and #3 carbs, with your petcock set in the RUN position. If you have fuel flowing, you need a new petcock. If no fuel flows, pull the vacuum line from the #2 carb nipple and apply suction to that line. If fuel flows from the petcock when you do this, it is working correctly in the run position.

Next, with the lines still removed, turn the petcock to the PRI position. If fuel flows in that position, you won't need a new petcock.

If the above mentioned steps fail to yield the results listed, DO NOT try to rebuild your petcock to save a few bucks. MOST have had limited to no success from the rebuild "kits" and you run the risk of repeating the problems you are having now.

The fact that you have raw fuel leaking out of the carbs OR into the carbs, tells me without a doubt, that your floats aren't doing their jobs OR that the float level is set too high.

Just want to add, sometimes you need some vacuum to get it started but once started should flow freely in the Prime position.
