I have a 1975 400 I am considering selling. I have a 60" deck with it. The mainshaft for the mower gearbox was bad. I bought new bearings for it and have the new shaft. The engine was running good but it smoked at high rpms. The fuel pump crapped out on it but it ran fine on a test remote tank feeding with gravity to test to see if it was the fuel pump. I am in southern nh if you are interested let me know. Headlight is back on.
