Hello I recently purchased a used x7 2 stroke for $150. It ran fine when I purchased it but I lost the key on the way home. I was able to turn the ignition with a screwdriver and pullstart the engine. I made it about 200 feet down the street before it died. Just cut off, did not bog down or sputter out. So, I am going to start off this project by replacing the ignition and hoping that will solve the problem, although I have a feeling this isn't the case! I added fuel to the tank that only was 1/3 full when i bought it so that could possibly be the problem aswell (bad fuel). Any tips or ideas are greatly appreciated!
