Hey everyone. I recently got a moped I found in my grandfathers shed. It had about 7k miles on it but it looks like it is in almost perfect condition. Since I got it, I have had to put it two bran new tires and tubes, a starter/drive v-belt. A new Drive chain, and I had to clean it up and everything.
So this is the problem, The engine will start up fine cold, I can ride it for about 10 minutes, then If I come to a stop and let it idle it will die. Then when I try to start it back up again, it will not spark. ( I have not verified this but I have been around these 2-Stroke engines and I can tell buy the sound and the way it feels that it is not sparking. I have taken apart the carb when I thought it was a carb problem and I know it is getting enough gas.
I can ride it for as long as I want, (I have only gone about a max of 30 min) but I just have to keep it revving when I stop.
I have also found that after the engine warms up, about 3-5 minues of riding there is almost no performance. The engine bogs down and can barely make it up a very small incline. The engine also max's out at about 23mph where I know that I can get it up to about 32-35 when I first start it up. So this leads me to think that it is not fireing all of the time...
So I am almost certian it is an electrical problem. I have not even looked into taking off the flywheel to get to the points and condenser because I want to know if there are any tricks to do so. I have found some coils and consenser for this online on ebay for about 40$ and I was looking into getting that. But I want to know if anyone else has had this problem and there may be a cheaper or easier fix
Thanks in advance!
