Hello, this is my first time on the forum! I purchased an 80cc 2 stroke engine kit and have been using it for about a month and a half now but recently I haven't been able to get it started at all. The carburettor had been leaking fuel for a few days prior so I fitted the High-Performance Carb that I'd ordered - no leak thankfully but still no start! The spark plug and CDI are still in working order so I'm baffled as to why there is no ignition. Some mysterious yellow fluid has appeared inside my carburettor, however. If anyone could offer a little insight into my issue I would greatly appreciate it.
