Greg,
I will look tonight how my carb is set up. I was out last Friday and it was about 92 deg out and I was running a 158 main jet and about 2 turns out for the air screw. I assume that I am running a K27 needle and probably the 5.2g float but I am not certain – are there stamps on the float and needle indicating what type they are? I will check out all of the other settings on the carb this evening. I am planning on spending the day at the track tomorrow with a forcast of 72 to 80 over the course of the day. I figured I would start at a 155?
I understand that the Rotaxes don’t like being off throttle, but I after the engine bogs at the exit of 1, I don’t get any throttle response at all until the ledges at the exit of 4.
Thanks for the help
