i was hoping for some help clarifying the c/p class engine rules.
"Engine must be originally manufactured for use in lawn mowing equipment and be stock in
appearance, with the exception of air filter, air cleaner or velocity
stack. Crankshaft must be in original orientation and clearance hole in the frame.
Engine may be internally modified"
now could i put any lawn mower carb on these motors, which brings my next question, would it have to be a stock manifold or could i make one, if not could i weld it or make a carb adapter, what is considered stock appearing? would a valve cover spacer or billet valve cover be not stock appearing, what if i were to paint a valve cover spacer, wouldnt that "appear" stock. the reason i ask this, is we tractor pull and have alot of r&d in are kohler carbs, and would like to put one on a kohler command single ohv engine in this class, but i am not sure if that would be legal, i just find a hard time interpreting the rules, they seem so veg, any help would be appreciated, i am not trying to cheat, i would just like to know what is considered stock appearing, in my eyes a stock kohler k series carb would look stock, the adapter could probably be a 1/4" thick and i would think that would fit with in the rules, but i am not 100%.
