Hi as you guys know, i changed my carb for a new one and also changed my fuel line. my hard start issue stopped so the hard start was cause of the carb. i was having idle issues but i managed to fix it. so after 2 days of enjoying my scooter with the new upgrades, all of a sudden my scooter does not want to stay on, when i let go of the throttle it stops? and not only that sometimes when i start my scoot there is a really loud metal on metal grinding noise for like a second, i think its the starter, i think i want to shoot myself now, 2 problems back to back
by the way, * i checked all the hoses for holes * checked to see if the plug was plugged * cant be my fuel pump cause i can see it working with my transparent fuel line, * its not the fuel filter, carb or fuel line (all new) * played with the mixture and idle but nothing happened

2 days is a great start!
Try adjusting the valves, another not too hard thing to do. Have you downloaded a manual?
How did you check the CDI.
Have you check it for spark at the spark plug?
The metal grinding sound does not sound good, check the oil for flakes of metal.
One more thing, when you try and start it, does it turn over faster than before? You may want to check the compression.

The metal grinding sound does not sound good, check the oil for flakes of metal. -- checked dipstick, no flakes One more thing, when you try and start it, does it turn over faster than before? You may want to check the compression. -- what do u mean by turn over? and how do i check the compression?

Seems to me like it is running out of gas. Starts up so the electrical things are probably ok. I know you say you can see gas in the lines but it may not be flowing, just sitting. Try spraying some starting fluid into the intake when you start it and see if it continues to run as long as you are spraying it in.

Update:: ok i left the scoot at the mechanic shop, they said they will check it, its a real motorcycle shop so they what they are doing, found a cheaper option than a tow truck. I rented a pick up from Uhaul, lets see what happens...stay tuned folks, in the mean time, i saw my favorite motorcycle there, i did a small video, i think im addicted to making videos, lol

Update:: Ok guys, are you ready to know how much i got ripped off, the total was $165.00 here comes the good part, the mechanic said it was 2 things. He said the fuel line that i replaced had too much slack and the fuel pump wont have enough power to fuel the carb. And the second part was that the mixture and the idle speed screws were off. Now the reason i had some slack was because i wanted to put my fuel line in a downward angle plus i wanted it out of the way so i can put my bucket storage thingy. I did have some trouble adjusting the idle mixture and speed screws. The mechanic made my fuel line how it was stock, which is more of a straight line so i guess making your fuel line in a downward angle for better fuel flow is a myth...well there you have it, the scoot is running fine now, Ohh and dont forget i wasted money on a Uhaul pick up to bring the scoot to the shop...smh Lesson Learned: never re-route hoses or fuel lines

I am glad it is running but I think that was a strange diagnosis and treatment. Longer lines would increase line resistance but I would not think that much. The carb screws seem like a more likely cause, but you had it running and why didn't it not run from the get go.

The carb screws seem like a more likely cause, but you had it running and why didn't it not run from the get go. it did run for only 2 days thou after installing the new carb, then all of a sudden, it didnt want to stay on (idle) the mechanic said that the fuel pumps that come with the scoots are terrible and that having a fuel line with less slack makes the fuel pump work better. So i guess that with the idle & mixture screws issue, that was the problem, that motorcycle place is a necessary evil i guess, i will continue to work on my bike & leave that place for my last option. Little by little im upgrading all my parts on my scoot so i wont have any issues in the future

Most of these use gravity for a pump. They do have a vacuum powered valve. That opens up after it starts running to allow fuel to flow. The scooters with the tank mounted low in the floor of the scooter do have a pump and yeah those are not the best, they are easily replaced though.
