Hi I have been working on a aerox 50 for my son , it has been running Lovley as it has had new barrel piston and rings new electric choke new exhaust , but the other day on his way to work it lost power and cut out , I have had the carb off and cleaned it out , it starts first kick and idles Lovley but on riding under load it just dies , as if it’s flooding or not getting enough fuel ? Any ideas please
Air leak? Spray some brake cleaner around the intake manifold area with it idling. If it either picks up or dies, there it is..... Also, did you jet the carb to suit the new exhaust properly? Might want to do a compression test as well, just in case.
Hi Steve it’s a new barrel and piston and rings standard 49cc the exhaust is a standard exhaust so I didn’t rejet it but it was running Lovley for weeks then just started playing up
