In Reply to: JD70 LP question posted by JPFL on January 10, 2013 at 19:00:13:
I have got a 70 LP and I recently had the exact same experience. It turned out that the aluminum passages through the Century vaporizer/regulator had developed pits where the gasket surfaces should not have any. By the way, no, there should not be any direct contact between the propane and the antifreeze/coolant. What I did, that fixed my problem is, I got about ten sheets of 120 grit sandpaper, and sanded both the body of the regulator/vaporizer and the cover (the one that doubles as a mounting plate to the bracket on the tractor) , until it they were really flat. I also used a little JB Weld to speed things up. I did it about 5 months ago, and after installing a new kit from Carb & Turbo Systems, it has performed flawlessly. Good luck, and be persistent, it's not rocket science, it just takes a lot of effort to sand it really flat and make it leak-proof. Hugh
