Hi guys I recently saved a sym Raider 600. Unfortunately, it was disregarded by the previous owner and badly treated. I had the problem that the exhaust was defective. That’s why I changed the exhaust to a tuning de-sonic damper with ABE. Then it went out due to low speed. When setting the speed I got out the adjusting needle and I don’t remember how the setting was before it was. You’re black. Could someone tell me what the basic attitude of the carburetor would be? Or what I could do? Would be really grateful. Thank you very much.
