Have you checked the choke? If it is choked closed and the linkage is stuck, you'd be turning about 3300 RPM sitting still!WTF... I got a 90 yj 258 w/weber and nutter. I just finished an paintjob & overhauled the top half of the engine but also had most of external parts disconected inc coil, wireing harness, manifold ect. Now with everything back in when i started it it ran wide open (sounds like 4000rpm> throtle linkage is connected good> thats without depressing the accelerator. I think its a wiring problem but without the gas how can it rev so hard.
