Totaly hacked off with an f 4.6 engine just wont run right or tune got no air leaks got good back pressure good compresion did have new plug till it bernt out running 25 percent nitro will only start wen it rich basicaly factory settings so then it just cuts out as soon as u go near the trottle becuse its so rich so i lean it out quater tern on the hsn so it will run then it shows realy lean condition over heats and burns plugs out so it will ether be so rich it cuts out or even an 1/8th tern leaner and it will over heat and bern plugs
