Also attached... Here is my dilemma.. I have a 50cc scooter It was garaged for two years I worked on it and goit it started and it ran well for a couple times. I then took the scooter to the store and came home in the rain. I tried to start it a few days later and… The scooter would start and then died… WAROOOMMMmmmmmaaaww…….. I knew that my gas cap was broken and figured that water got into the fuel… So later that week I took the entire scooter apart to get to the gas tank, carbs, etc… I drained the fuel tank. Replaced the Fuel Filter. Cleaned out all the fuel lines. Removed the little “silver thing” in…out….valve… thingy Blew on it just for good measure for whatever reason Remove the Carb.. Cleaned the Carb Cleaned the air Filter Put everything back and… Still it Starts and then dies. It will run for 2 seconds and quit. I let it sit for a week and just tried to start it and it started and quit after 4 seconds..2 seconds longer. I have done the above two time to make sure I did everything, Still I am at loss. I turned the screw 1.5 times and still nothing Another question I have is…remember the little grey thingy that says in ..out ..valve… there is nothing on the valve nipple.. Only the fuel line coming “IN” from the fuel filter…Fuel line coming “OUT” to the carb and then on the little grey thingy with four nipples…on the side there is a tube coming out …leading to the carb…. “Why is that line wrapped with a spring wire..also?
I am dying to go out to the beach for the 4th of July, but will not be able to make it without my little scooter. Does that little grey thing need to be above the fuel filter…that Is in height? Should I plug up the thing that says valve? How long do I wait until I turn the screw again, 2 mins? What wait? What is the reasoning? I noticed that there is a small brass screw on the top of the carb..what is that..? Please help me..i am melting in this heat. Thank you so much.

Since you are in a hurry to get up and running I'd try a couple things. Run a line right from your gas tank to the carb and bypass the vacuum fuel valve (the silver thingy). That way you can take it off of the table as a source of your problem. You don't really need it, it's just a backup in case your float valve fails. Make sure you plug any vacuum lines coming from the intake manifold that you may undo. The second thing I would do is set the valves, that needs to be off the table too. Do those things and we can pursue other culprits if it doesn't start. Rich
Thank you so much for your quick response. I am going outto the garage now. You mean plug up the little nipple on of the 2 nipples coming from the top..one is the gas and the other is a vac. So I will take of the little grey thingy and go straight from the fuel tank to the gas filter to the nipple on the carb and then plug up the nipple that was going to the grey thingy. Going out their now. How do i do i set the valves? Thank you again so much for your help..I am so excited...
Okay Bashan, I went outside, removed the grey thingy and the two tubes leading to the carb, plugged up the nipple on the carb and replaced the black fuel line with a clear one so I perhaps see what was going on. Note: fuel no is going straight from the tankt>>> filter>>> carb. Still .. start>>> run for 2 seconds and dies… I turned the screw all the way in and then backed it out 1.5 turns. Played with the screw for several adjustments and tried to restart….still the same. I did see a small brass screw on the carb by a black thing that had wires that was also on top of the card. I loosened that screws while adjusting the other screw and got worse no start…So I figured that that little screw on the top was maybe messing up with the air that I did not want to go in the carb. Since I already plugged up the other nipple. Do I have to wait for a few minutes after I turn the screws on the side of the carb to start testing again? Thank you so much for your help.
