Hi I already posted about my idling problem, but I'm also wondering what could be wrong with this new problem...... So I will ride downhill and the engine will sputter and sputter until finally it starts up, I run out of road, engine shuts off, then it takes SO MUCH leg power to get it turned over and running... I really need to know why this won't turn over easy. I seriously need like full energy and a quarter mile... Please answer and give me tips, I know other people have already asked this on other threads but those aren't really working for me, I need something specifically to my bike. I have taken the carb apart and made sure it was squeaky clean! I also have some pics of the bike... It's an 80cc china engine(great...) and I just don't know what to do to make it turn over easy. I am very tired and out of breath. Thanks!
