Hi everyone!
I just had a question that you might be able to better answer. So I have a 2 stroke 49cc engine from China and am having some difficulty starting it now that winter is over and was wondering how to better troubleshoot it. I bought this engine last August and it ran great before it got cold. Before winter I stabilized the fuel and cleaned the carb thoroughly. I looked up the guides on this website and followed the basic guidelines. I checked the sparkplug and replaced the cheap one with a new NGK one. There is a spark when the clutch is engaged too. I replaced the carb due to finding a crack in it, and I also put brand new fuel (91 octane rating, premium grade) with it a bit on the leaner side just to try and get the engine started. I checked for leaks and can't find any in the engine. Before starting it, I took off the cylinder head and cleaned off all the carbon buildup. There were no scratches or visible damage inside. When I put everything back together, I still found no leak. I tried running my engine yesterday, but couldn't get it to run after 45 minutes of tinkering. I'm not sure what else could be causing the engine to not fire. I also unplugged the kill switch to give the spark plug more juice, but that was unsuccessful as well. When I turned of the fuel lines with the clutch engaged I did get a few kicks, almost as if the engine did want to start and there was too much fuel. I also have not adjusted or tuned the carb, and I'm not sure if that plays a role in this. If so how would I tune the carb without being able to start it? Any basic guidelines? Or any advice as to how to get the engine to start? Any help is greatly appreciated! Thanks!!!
