Pull the vacuum hose off of the nipple on the intake manifold in front of the carb.

Spray some carb cleaner or dribble some gas in the intake nipple and see if it fires. If so then you need to figure out why gas isn't getting thru the carb.
I've got to leave for the dentist now. I'll check in when I get back.

is there any way of checking the side stand kill switch? just to check if thats causing it? If you are getting spark while the plug is grounded on ther motor it is not any kill switch. |

Get the right regulator/rectifier for it and do what Terrilee says, check your grounds.

With the plug out it sounds different while turning over because the piston is not making compression. All of the air is rushing out of the spark plug hole.
I watched your video again and I still think it is turning over kind of slow. When you hook up the a car battery does it turn over faster?
Also, when checking for spark the tip of the plug should be grounded on the engine valve cover not the frame. The engine needs to be grounded good for spark to happen.
Once you have verified good spark and have the plug installed we can check for a fuel flow problem. Take the vacuum hose off of the nipple on the intake manifold and spry a short blast of carb cleaner in the nipple. Replace the vacuum hose and try to start the engine. If it pops or tries to run then you have a fuel flow problem and we can diagnose that.
As for the CVT cover bolt, I am not a welder. Depending on where the bolt is at I would try to get a pair of vise grips on it to break it free, or drill it and use an easy out tool.

In one of the owner's manuals I have it says .002 inches. I set mine to .004 inches because it seems to run better.

The brake lights should only come on when the key is on and the brake handle is squeezed. Doesn't matter if the engine is running or not as the brake light is fed by the battery.

With everything hooked up and working properly at idle the fuel flow rate may be so slow that it will be hard to see. Is there fuel in the carb bowl?
Try spraying carb cleaner directly in the vacuum nipple on the intake manifold and see if it will fire.

Yes, check for compression. Also to see if it is a fuel issue take off the vacuum line at the intake manifold and spray a little carb cleaner into the nipple. Replace the vacuum line and crank it over and see if it fires.

The Vespa 150's has more horsepower than the gy6 150cc chinese engines.

Funny you are in Shelton Wa. I am in Yelm. Are you at JBLM? Not since '86, but it was just McChord then. |

I believe this scooter has 10 inch wheels. You are looking at a stock max speed of 55 MPH at best so your goal of cruising at 50 MPH is pushing it. If you don't want to get a scooter larger than 150cc then look for one with 12 or 13 inch wheels. That will up the top end speed a little.
As far as fuel mileage goes, with a 150cc you can expect around 80 MPG +/-.

Sounds like it is running lean. Try adjusting the air/fuel mixture if it has an accessible screw. Alleyoop has a good write-up on how to do this here. itistheride.boards.net/index.cgi?board=tt&action=display&thread=12The high/inconsistent idling can also be cause by air leaks in the air filter housing,air to carb connection and intake manifold. Make sure all of those connections are tight. |

No that is a bit too tight. Try .1mm (.004 inches) on both the intake and exhaust. That's what my 50cc engine likes.
Here is a good video on adjusting the valves. You don't have to take the fan cover off. Just make sure the holes in the cam are lined up like the video shows.
