Hello, I just bought a scooter that has been sitting a year. Was new in 2010 and on the odometer it already has 7K miles. Personal scooter not retired rental but was told it was parked when a friend put 2 stroke gas oil mix in it and it died. I have pulled the carb and cleaned it, all vaccum lines replaced, new plug. It will not start. It tries, fires over but will not run on its own power. Already adjusted valves on it. Even straight shot of starter fluid without a carb attached and nothing just a little sputter then nothing. Off name brand scooter in the 50cc range. Anything I am missing here or did I just buy a parts bike being it still looks very new.

check the compression pull the plug and hole your finger over the plug hole with the throttle wide open it should blow your finger off the hole with some force

OK here is a new twist to the scoot. I can get it to fire and run as long as I hold the start button but as soon as I release it ... poof it dies. Lots of white smoke spouting from the valve cover return hose yet nothing at all but little pops from the tailpipe. It does blow my hand off with force pressure so not clogged but no smoke or exhaust there. Another question added too ... back in 87 my scooter had no kill switch, just a key to turn on and off. This scooter has no kill switch either just a key and the yellow start button. Is there another kill type switch somewhere I am overlooking?

Check the crank see if it wobbles on the variator side. If it does you need to do a complete tear down.
Would need
Crankshaft
gasket set
BBK with head
flywheel puller
I get 9000 miles on 50cc crankshafts b4 they come loose. They are time bombs.
Cylinder heads go bad the valves just get leaky.
50cc pistons, cyl seem to hold up for 18000 miles +

O.K. back in the saddle finally. Got rid of the cursed scooter, found it had a cracked piston. Now sporting a 2012 Sunny 150 by dongfang. Runs great and smooth but typical cheap few parts broken on it needing fixed. Was purchased originally from scooter depot so no faith in them helping fix it. The mirrors are junk, turn signal flasher already dead and the speedometer gear in the wheel is wrong. It will go from 0 - 70+ in 3 seconds and I drive 100 miles before I know it. Scooter depot has problems trying to send just a correct gear. Engine runs strong and tight, probably does hit at least 55 mph but will know for sure when I fix the gear. Will get a pic on here soon as I get a new SD card for my camera. Anyone with any knowledge of these scooters shoot me a line here. color is the deep blue on charcoal grey very nice. reality has at most 200 miles but since the gear is wrong it is reading 650 miles. Am changing to a nicer looking cluster with a tach soon as well so don't care what this one says for now.
