Hi, i have a 2008 flyscooter La Vie 150cc scooter that i was given by someone that wanted it out of their garage. It had been sitting for a couple of years. First thing i did was drained out the old gas, cleaned the carburetor, and installed a new battery.
Now it runs great, it just will not idle until it is fully warmed up. I can hold the throttle open to get it to idle, but if i let go of the throttle it quits. I checked the electric choke, and when cold the plunger is pulled up, and as it warms up the plunger extends. I also purchased a replacement and it did not change it at all.
Im not sure where to go next with this. can anybody point me in a direction of somthing to check?
Thanks

Warm it up and see how it idles as you may need to raise up the idle speed . Did you remove the bowl and both jets when you cleaned it ? Any intake , vacuum or exhaust leaks ? Cleaned the air filter ? The pecock may be worn and not delivering enough fuel at idle since vacuum is much less than when riding

When it warms up it idles great. i had turned the idle up to getit to idle when cold, but then once it warms up it idles so high that it will engage the clutch and want to move.
When i cleaned the carb, i dissasembled the entire carb, soaked it in my bucket of carburetor cleaner, blew out each and every passage and get with air, and then re-assembled it.
No intake, vacuum or exhaust leaks that i am aware of. there is one hose that is not connected to anything, but i think it is some sort of emissions thing. Because it is coming off of some canister that is also connected to the fuel tank vent, and the intake hose between the filter and carb.
FIlter is nice and clean. Scooter only has 1350 miles on it so i dont think it would be overly worn out. It is just strange that it will run just fine after it has warmed up.

My 4T ran like crap with a huge power loss when a hose on the airbox came off . The vapor cannister may not makea diff if unhooked but the other vacuum hoses like from the intake to the pecock are needed . Have you checked the valves ? Often if too too tight it may prevent starting or not start at all and is common . Since you says yours starts up but does not run good until it is warm your may be loose or have too large of a gap . Now mine got loose . It started and ran perfect but would want to stall just before coming to a stop . Have you adjusted the air/fuel screw ? Most run it all the way in and turn it 2.5 turns and adjust according on a warm engine . My 2T had idle bugs at times and I had to adjust the idle speed when the temps changed . It got worse with a BBK but I got a larger idle jet and now it purrs at idle . When its winter it will idle higher than normal at first and idle down after after a minute or two of idling since I warm up my scooters prior to riding more so in winter time . I ALWAYS use the CS ( center stand ) instead of kick stand since I would give it just enough throttle to turn the wheel ( not race the engine high ) in order to warm up the belt when its very cold . My Echarm has a killswitch in the KS which prevents it from starting with it down to prevent it wanting to roll and fall over if on the KS and idling high . My 2T would sometimes spin the wheel at idle in winter since RPMs were higher but stiffer 1.5k clutch springs stopped that since they engage at 1,500 RPMs higher than the stock springs . One of the advantages of having of having EFI on my Echarm is instant starts and idle is always the same regardless of weather or engine temp , plus better MPG and performance compared to a carb .
