I put my 48 LA on propane in 1957 an bought the kit. I posted this before but here it is. I bought the kit which had, new head,tank, reg, carb, I also put in new Sleeves and pistons. Painted it all for $404.00.. The 48 LA had more power than the ones through 47. and when I went LP it uped my power and did not use more fuel per hr. than on gas. I pulled a 15ft oneway the first time over and a 15 an 12 ft togather the second time over. and than two 12ft. rod weeders. or a 16ft JDCC Cuilt. with 16 ft of rod behind.
