A good trick shown to me by a mentor that taught me the "rope trick" is to tie dental floss around the keeper groove on the valve. Push the valve in and fish the floss out of the upper spark plug hole with a piece of safety wire with a small hook bent on the end and pull it up by the floss to clean the stem. After cleaning the guide when the valve is back in the cylinder bore, fish the floss back through the guide and it usually pulls right back in.

Nice video! Reminds me of a joke about former gynecologist looking to become a mechanic, who took the engine apart and then built it together -- all through the muffler!

Another informative video based on many years of experience!

I’m an auto mechanic and find it amazing how you did that without putting the head!!

Thanks for this educational video. It helps me to understand what the stick valve problem is, how to fix it. I am now more conscientious in leaning the engine while taxiing! Is there any product that dissolves and cleans the carbon deposits to prevent the stick valve problem?

Compressed air to hold valve in place. That's how I have replaced valve seals on automotive engines. Wondered why in aviation everyone seems to use the rope trick. Would it have been a good idea to lap the valve while you were at it?

Add four ounces of Marvel Mystery Oil to each ten gallons of gasoline in fuel tank. You will never stick a valve again. This has been a sure bet for almost a hundred years. ‘costs almost nothing.

What is the likley cause of a sticky valve. What do you recommend to prevent this from ocurring. Running as lean as possible? Additives? What would be the likely cause if it is a recurring problem?

How do you get the rocker arm and shaft back in? Thanks for the vid

I have solod on 150 one of the people in millions I am sure.😂😂😂😂😂😂😂

Any reason this wouldn't work on the larger Continentals? Like the 520?

Did you use a specialty valve guide reamer from McFarlane?

[robertwilson]

Waste of time, the guide is worn and will get stuck again. This is only a good technique to get a airplane back home. Not at annual, needs to be removed and repaired properly

Do you shake your customers hand with your right hand covered in very infectious warts. Yuck such a turn off.
