I have a TGB Akross 50 cc.Engine cuts out when going down hill. Engine sluggish down low. How do I fix this?

Scooter is not Atlantis city but a Akross with a 70 kit , performance exhaust. Lately the engine seems to be bogged down, then last night , when travelling down hill the bike would just lose all power. I hit the brake & ignition & the bike restarted. I'm using km/hr , so it would be sluggish under 40km but once over this point it was fine upto about 65-70km. it was only cutting out under de excelleration / downhill. Any ideas please?

Not enough exhaust flow will cause it to be sluggish -- open the exhaust up so it breathes.

    you are losing fuel pressure to the carb. you need a bigger diameter gas line feeding the carb from the gas tank. this will give you more gas to the carb. sounds like you are running out of fuel when going down hill. so check your carb float and bowl - make sure everything is clean and floats. Back to your exhaust you need to -- in your baffle area is where you need to increase your flow -- you can buy an after market exhaust that will allow more air flow to flow out of your bike and it will run much better

I was goin down a road at full throttle, around about 50-55 mph then all of a sudden i lost power and my 50 cc moped was runnin all sluggish, so i took it to a specalist he says its not the engine its...

Your description sounds more like water condensation in the gas than electrical. Drain the carb and install a new spark plug. If I am wrong, then you have only lost the time used in draining the carb, and a new spark plug is always a good thing anyway.

Cooling system

Probably if you change the whole engine. Remove the cooling system and replace the cylinder and head for ones with air vanes on. But that would probably cost nearly as much as a new scooter.,
