Looks like I need to do some more adjusting to get mine to turn as fast as you guys. av8tor1977 & RCIGN1, what kind of carbs do you have on your engines? Same for the mufflers? Any suggestions for me on how to get mine to run faster? I am currently having problems getting mine to run with a Walbro 324 wide bore carb when I open up the choke all the way. I have a velocity stack installed but I am still using the stock muffler. I have yet another Walbro carb to try but the bore is not as big as the 324. I also do not know a good starting point for the needles as I've had them all over the place. Any help would be greatly appreciated.

Thanks
