been fightin my minnie moline big mo500 loader backhoe. 4cly gas 206 cu in. way too much under hood heat. fuel tank sits behind motor, front mounts to exhaust manifold on one side, engine block on other.builds up so much heat after a while it will boil fuel in gas tank. was digging the other nite, noticed exhaust mainfold was brite red, dang near could of brazed on it. opened the main jet to put more fuel to it, brought the color down alittle but still looked to hot to me. tractor runs good otherwise. im gonna try setting valve lash on exhaust a little looser, book calls for .010 hot, ,018 cold. timing calls for 27 degress at 1750 rpm. thinking on maybe giving it a little more advance. engine temp runs 190 when hot, coolant doesnt boil over. any other ideas to get temp down? exhaust manifold is new, no vaccuum leaks, carb rebuilt. she drinks plenty of fuel so i dont think it lean. i been running her now with the hood off to get rid of the excess heat.
