Yeah we have observed the linkage in respect to the throttle and it fully engages. Even after manually opening the secondaries at full throttle and spraying a bit of fuel in it has no effect but we can see that fuel is entering the bowl.

I have limited carb knowledge so forgive any redundancies or if I out my foot in my mouth. But based on this discussion and my observations it seems like there is an issue with the secondaries interaction inside the carb not allowing the fuel to be converted into power.

I'll do some research and get familiar with the carb and see what comes of it.

Appreciate the feedback
