I recently installed an 80cc Samger Kit (China Engine) engine on my bike. At first, I had problems because the intake manifold was restricting the carburetor. I fixed that by installing a new offset long manifold. However, now I have two new issues:
- The bike only runs if the choke is fully engaged. It will idle on close choke but dies if accelerate
- There's fuel leaking around the carburetor. I've tried cleaning the carburetor and checking the gaskets, but the leak persists.
- I'm getting very bad fuel economy. The bike seems to be using a lot more gas than it should.
