Hey, and that’s what I bought a scooter the day before yesterday (Hercules PR5S 50cc). The seller assured me that the scooter when he got it ran what I believe it was. What the thing about it is he said he had had the long ago had built in still new battery. He might have said that it could be on the carburetor because he was told that this one had to be cleaned. Unfortunately, I have no idea about that because one might know what it is. I picked it up, of course, I thought it was because of the cold when it’s running and you stay constantly on the gas that stays on. I drove 30-40 minutes anyway it goes off. And you can hear when driving already so noises don’t know if anything is with the air. Thank you in advance for any help Please just express as possible because as I said, I don’t know about scooters and must first find out the shoot about the individual parts. And if any of you know where to tacho display or similar things that can be retrofitted, for the scooter knows gladly write thank you
