I take off and hammer down and dont get very far and the a solid alarm goes off and then it spits and spudders for a while then it will run again and do it all over again. I have replaced impeller,fuel filters and treated the fuel and checked the oil.put motor on computer and no code shows up.what do i try next.i was thinking spark plugs and maybe the thermastat. anyone have any ideals.bad sencer maybe.
