yeah, the antifreeze stuff works well. I tested it on my tower 46. I put it in and cooked it on and off for a while and it worked really well. You don't actually NEED a crockpot, it acts as a catalyst. I left a Super tiger 75 in antifreeze for a couple of months, and that worked really well, could just rub off the baked on stuff. You can pick up a small crock pot for less than $10. One other thing, I would make sure that you clean out the antifreeze out of the engine. What I do is wipe off as much stuff as I can, then rinse off the rest with isopropyl alcohol (here comes the flamage), wait for it to dry, put drops of after run engine oil in it (I use marvel mystery oil) all over. I mean every where. All the open spots. Then I gas it up on a test stand and go for it. So far, its worked well for me.
