will not stay running (idle)

[twinkalicious]

My 8 yr old girl won't ride with me anymore, too embarrasing. Here's my morning routine with my 2007 250 scooter bought brand new two months ago, start it ,wait for it to get to 2000 rpms , gas it, make it 50 yards or less puhhhhhhh, dead. Either wait a minute for it to rest, or crank for a year or until the battery is almost dead starts up vrrooom until a signal is red because i havent timed it right to hit it green. puhhhhhh dead. if it has it's minute rest it starts up again, but if not the cranking thing, honking flipping people off. you get it. have read hours of q's and a's and have changed carb checked this , that did everything all the suggestions ive seen. There is one thing about adjusting the idle screw and mixture screw which is on the bottom of carb just to make it a little harder im guessing, How am I supposed to do any of that when it will not stay running for more than (if cold for about 45 seconds, of hot 3 seconds) it wont idle long enough for me to find the idle screw before it dies let alone try to do the mixture screw. im blind from reading , embarrased to ride it piss neighbors off in mornings trying to start it, i bought one and a month after i got it someone turned left in front of me sending me over the bars and then they took off. total loss got another one , two months into this one im looking for the car to turn again in front of me so i can just wash my hands of them. So any parts from the back of radiator and back ive got, have tried switching carbs , same thing have switched them back same thing. please help cant afford another one.

First thing to do is check the valves Top Intake .004 inchs and Bottom Exhaust .005-.006 inches. Ususally you will find that the Bottom Exhaust will be tight. When that happens it looses a lot of compression and they will not hold the IDLE and or Die and Hard to start.

Then Even before you start it find the IDLE SPEED SCREW don't know what carb is on there but it is usually on the Throttle Cable side or on the LEFT side of the carb. But find that screw and turn it 1/16 or so to the RIGHT it does not take much to bring up the Idle. What is actuall is doing is opening the BUTTERFLY just like it does when you twist the throttle.

Once you get it to at Least staying Idleing we can work on the Fuel Ratio IF it needs it.

It would help if you could put up a picture of your Carb Left and Right side so I know what I am working with.

I adjusted the valves and it seems to have done the trick for now. Thanks for the help , i'm finally happy to ride it again.

FANTASTIC!! Get your daughter back on that scoot and see her smile from ear to ear.

When my granddaughters come over they always ask if I can take them for a ride and of course Grandpa obliges. They have a grin from ear to ear they even tell me to put the radio on. ;D

wile...good job....you got the fella back on the road...where scoots belong..and as you know....some of biggest problems on these things...is such a simple fix...that people tend to overlook the small things...and all but completely disassemble the engine in search of something majorly wrong...
