Hi all! First time poster long time three wheel fan!

Help me get it running!

I’ve recently got hold of an 84 Honda ATC 70 which has been sitting in a container for 20 years. Over the coming months I want to get it running, have some fun with it and try to preserve this awesome machine!

It has a jincheng 50cc engine in it which I plan to swap out when I find an original motor but I’d love to get it running in the mean time and that’s where I need help as I’m no mechanic but I’d love to learn!

We now have spark, I have cleaned the carb out and I’ve attached it to an auxiliary tank to ensure clean fuel whilst I work on the original tank, no dice.

It runs for 10 seconds or less with the help of break cleaner then dies!

Any ideas? What can I do next? It feels like a fuelling issue. Do I try cleaning the carb more, can I test it at all? Any help is greatly appreciated!
