Ok, the Murray I got from brystheguy runs, and starts up first pedal everytime, however when actually driving it it starts acting funny.
I was just out riding it and at first acceleration was pretty weak as it has been since I got it. I got it up to about 21mph at full throttle. Then after a couple times down the block and back it started to feel like it was 4 stroking at full throttle then all of a sudden I got a surge of power that shot me up to about 28 mph. Then I slowed down and stopped to wait for a car. After that it ran even slower than before. I mean like 10 - 12 mph at full throttle.
I'm fairly certain it's running rich, but could running rich cause it to act like it is?
