I have two H"s, one is a 42 and the other a 50. The 42 was originally set up to run Kerosene, it has the dual tank, used to have shutters, and had the exhaust diverter (long rusted away). My grandpa bought the 42 new. The question I have is a difference in power. The 42 has significantly more than the 50 even though they are the "same" tractor. Now, on the 42, my dad told me once that the head was changed when grandpa no longer wanted to run kerosene because the kero head was a lower compression head. On the head itself is stamped a large letter "H" which either my dad told me or I heard somewhere (or think I remembered!) that means this is a high compression head. Does anyone know how I would find out? Nothing life or death, just curious to know why the difference in power between the two. I have rebuilt both engines and the 42 got flattop pistons, the 50 got thinwall sleeve/hightop pistons and still the 42 has more power.
The other difference between these two is how cold blooded they are. The 42 is AWFUL, the 50 is not. If its winter, the 42 has to have the choke nursed for a long time - even in the summer you have to watch the choke when its cold. The 50 will usually start even in the winter with litte to no choke unless it gets down in the teens.
Thanks!
