Engine performance relies on the condition of the valve. Worn stems or guides are burned or wrongly seated valves let gas to escape under compression and this result in poor starting and power loss. Valve seat inserts suppliers explain how you can enhance the condition of your valve.
Valve springs can also affect the performance of the engine. With time, they get weaker and cause the valves to bounce on their seats.
How to remove the valve?
Support the cylinder-head assembly firmly on an ideal work surface. Make sure that there is enough space to store parts as they are removed, and cardboard boxes and clean newspaper should be there to keep them clean and safe.
Fasten the nuts and bolts that are securing the inlet manifold to the cylinder head side, remove it along with carburetor, if possible.
Make sure you put the carburetor assembly in a clean, safe place on a newspaper sheet. You must remove the exhaust manifold in the same way from the head side and place it with the inlet manifold.
Undo the bolts or nuts and secure the thermostat housing to the cylinder head. Easily remove the cover and lift out the thermostat. If you think there is a need of unscrewing and removing the temperature gauge transmitter from the cylinder head side, do it. Turn the cylinder head and support it on blocks to expel the valves. Put a valve spring compressor on the valve nearest the head front.
Compressing the valve spring is next step. Continue doing it until the two split. By this tapered collets round the top of the valve stem can be easily removed. Make sure you should not drop them as they are easily lost.
Then release the compressor until it is free, and remove the valve spring assembly and eject the valve from the head.
How to remove the carbon?
Remove the carbon deposits from the combustion chambers and valve ports of the cylinder head with the help of a suitable scraper. You can use blunt screwdriver and a wire brush. Clean the head face to remove any unclean or remaining carbon with the smooth side of a hackshaw blade or a paint scraper.
