Yup its a great motor, You won't like it though it can be made into a real scary hotrod engine. So you might as well just send it on down to me. As for parts what ya want. Air filter (k&N) and adapter will run you 90.00. As for not touching internals, a cam wouldn't hurt. The stock ignition is junk. Best thing to do is get the billet flywheel it then uses 12hp briggs coils, will need to diode isolate them, but will run great. Stocxk coils once hot start missing around 4500. Stock carbs are too small for it to run any kinda rpms but if you don't put a cam may be ok. Won't start without choking it though unless you get the bigger carbs and have the internal jetting modifed. Full set of carbs built ready to go will run you 240 each.
