It idles at around 1800 RPMs full power is around 6500 RPMs and the needle valves are set at the factory settings I did recheck them and I did reset the needles on the low end it is set at 1 and 1/2 out from fully closed and the high-end is set at 1 and 2/3 from fully closed. The only problem I have is trying to get it started once I do get started it runs very well where the needles are set I just wanted to know if anyone else had the problems that I am having with this engine and if so what did they have to do to get it to start.
