I bought a Roketa 200cc quad that had been sitting for a couple of years. I ran it for a while then replaces a breather hose and cleaned the carb. I let a friend ride it. He rode it pretty hard and it quit running on him and started to back fire. I took the card off to clean it again and never could get it to run right so I ordered a new carb. I put a PZ27 on the 169 FML. my question is this a good combination? it runs now but I can't quite get it tuned. after researching and adjusting and more research and adjusting I can only get little over half way to 3/4 into the throttle before it starts cutting out. So did I buy the wrong carb? OR do I keep playing with the adjustments until I find that magic spot? Thanks for your help.
