I have a 2008 lambretta UNO 150. Really is Adly hammerhead 150
Thunderbike
I was cruising at 50 mph when scoot made strange noise and engine stopped working. Was able to coast to stop. Drive belt is fine, getting spark to engine and gas in carb.
Any ideas on what to do?

compression ? Valve gap adjustments ?
will

[cheapscooterguy]

I'm a novice at working on scooters. How would I do the compression test and valve adjustment? My battery went dead trying to start , got a charger to recharge

There are several videos on YouTube about how to do both things. great resource. I learned valve adjustments and many other things from there.

My Adly did that a couple of weeks ago. Once I got it home I pulled the sparkplug out and placed my finger over the hole and turned the motor over with the electric starter. Felt no compression while doing this. Pulled the valve cover off and found one of the exhaust valves stuck open.

It is currently at the dealer to find out the extent of the damage and to see how well Adly's warranty is going to work.

Thanks for info. Will try compression and check valves and get back to you.

Have you tried to kick start the engine to see if it will roll over???

[cheapscooterguy]

Yes I tries kick starting. No luck

I would set the valve gaps and then check the compression...
