I have had success freeing stuck valves using a product called 'Free-All' made in the US by the company Federal Process. I had a situation with an antique Chris-Craft wooden boat with a flathead six where all the 'usual remedies' had been tried and failed. It took a couple of good soakings but the valve let go and the ecstatic owner was never without a can of Free-All in his tool kit afterwards! I don't know what the active ingredient is in the product, that makes it so effective, but I have had it free threads and 'stuck things' many times over the years, when nothing else I tried would work. I know everyone has their own 'pet product' when it comes to rust breakers and thread lubricantss, etc., but Federal Process' product line is far and away the best I've come across. And, for the record, I am retired and have absolutely zero stake in promoting their products - just passing along 'what worked for me'. Chris

Thanks for the suggestion. I backed off the engine a quarter of a turn, then I filled the cylinders with a 50/50 mix of diesel and ATF. Then, I removed the carb and valve cover and endeavored to clean the valve area as best I could. I'm glad I did because I found a piece of wire from a wire wheel in there. I then soaked the where the valves pass up into the block and guides hoping I can get penetrant from underneath. While I had the access to the valves, I took note of which valves were open and closed and recorded it down. I let it go two weeks then report back.

Sounds like a good approach, without hurrying anything. Best of luck. Chris.

Success! After filling the engine with 2 gallons of a 50/50 mixture of diesel and ATF and waiting two weeks, the engine rotates without any problems. Whew! Now I just need to pull the manifolds to remove the excess mixture, but that is an easy job.

I can't tell you how happy I am that this is freed up, and I don't have to pull the whole thing apart.
