Hi there, I got an 80 cc motor I just installed and am barely braking it in. I have already ran a gallon and it has run rough the whole time. I am using 8 oz 2 stroke oil to a gallon for break in and I put a 68 size jet on the stock nt carb. I left the needle clip in the middle position and the bike has run like crap the whole time. Just last night as I was heading home riding I tuned off the fuel valve as I was riding and was surprised to see that the engine started to run great for a minute or so then it bogged down as it ran out of fuel. I opened the fuel valve to keep it going and closed it again to see what would happen and sure enough when I turn off the fuel the bike runs like a champ. By the way the fuel valve does what its suppose to as it is aftermarket quality sbp part. Any input on my situation would be greatly appreciated , thanks.
