Why do I know this Dealing with the exact same problem with my 47 - Granny - here is the thread - Stuck Valves. Pull the plugs on 2 and 3, pour in 1 tablespoon of oil, rotate engine by hand a couple times. Take the side valve cover off. Spray the valves/valve springs and tappets with your favourite penetrating oil. I like Nut Buster and Loctite's Solvo-Rust. Rotate the engine by hand with/without hand crank again but while watching the valves functioning. You should see whether it is exhaust or intake valves that are sticking. Take a standard screwdriver and very.. very gently tap the offending valves once or twice. I used a dead blow mallet to reduce the shock to the valves. Spray the valves in the spark plug holes with your favourite penetrating oil. Rotate the engine by hand a couple times hopefully twice each cycle. Continue to do this until the valves drop and drop they will. They are just stuck up because of carbon/oxidation.
After the valves have dropped, add another tablespoon of oil to each spark plug hole and hand crank the engine again. When you feel the valves are moving freely, add some SeaFoam to both the gas tank and the crankcase according to the directions on the label. This will help clean the valves/valve stems and guides. It may still take a bit to get the engine to fire up, but this is the first step.
Rudy and Eugene for sure. Not so sure about Boss, even though he said it first. did I say that.Joe Malinowski wrote:I 'd listen to Boss , Rudy and Eugene for sure, they have always given me great advice.
