Do you need a degree wheel for tappet setting or is there another way. thanks. Ken.
 
1. Remove the spark plugs.
2. Put a drinking straw in through either plug hole and rotate the engine to find TDC.
3. Check the tappets on that side. Grab each with your fingers and try waggling them.
4. If both have a little slack you're there. This means both valves are closed.
5. If not, rotate the engine 1 full revolution and now both valves will be closed.
6. Adjust both tappets on that side.
7. Repeat on the other side. Job done!

Notes:
a. At TDC on exhaust stroke 1 valve will be obviously pressed down (open).
b. I put the tx in top gear and rotate the rear wheel to rotate the engine.
c. This method (the drinking straw) is absolutely, definitely accurate enough to find TDC.
