Inherited a problem or bought a problem (one of the two)Bought from neighbor know it,s been running, pump was leaking from head like a lot of them .Pump was backyard repaired. .Tractor and pump came seperate to me. Timed 18 BTDC, pump timed no start ? Very little smoke .Thought maybe pump 180 out ,sent to bonified pump shop was infact timed correctly .Everything checked okay it,s on it,s way back to me .Pulled valve cover on 18 BTDC both valves closed and pump timed should start right ?Only done three so certainly still lot to learn any ideas ?Thank You !
