So after doing some reading, I have some ideas of what the problem might be. But I will post anyways. I have the 80cc two stroke engine. Stock carburetor. My low end acceleration is very smooth and fast. When I get up to about 20 maybe, the noise of the engine changes from a purr to a less smooth sound and at the same time immediately stops accelerating. Iwill jump back and forth from smooth to rough sound and each time it changes back to smooth, I have a jolt of acceleration. It seems like I am hitting a wall and not getting enough fuel or air. However, when not under load and just idling, I can rev the engine way up, but the rev is also not a super quick rev, I have to hold the throttle for about 3 seconds before I hit max rpms. I have a new carb coming soon, just want to know what this could be?
