I will get them as soon as I get to work in an hour or so, to adjust the valves you take the cover off the bell housing and you will see a pointer on the bell housing. On the fly wheel you will see three sets of numbers.you may have to sand the surface, rust off it. Start at #1 and go around to the next number in the firing order. You adjust both valves at the same at time the bottom of the bell housing.
