i would like about 55 or 60 hp . it works hard when i round bale wet grass for silage.so i was tinking i could turn it up a bit .I am a diesel truck mechanic and i have seen what to much fuel can do. IT runs just at 180 on water temp under laod .i dont think it is getting enoulf fuel to keep it at temp .The compression is ok it starts grate now cold better than my 1971 IH diesel.It does have some vapor that comes out the crank case breather not too bad .
