SBOT

I recently used the anti-freeze crockpot method on an old super tiger .40. It worked great making the engine look like new again, but after the crockpot cleaning the engine had very little compression. Did not seem to hurt the preformance any; it starts easily and runs great, but there is very little resistance at TDC. If I used this method again I would remove the piston and liner maybe the crank and just clean the case head and muffler.
Then again like I said the engine preforms well; just feels strange flipping the prop. This engine used to really snap when you flipped the prop thru compression.
