When to use TDC between compression and power strokes?
During approach to (TDC) between compression and power strokes when both valves are closed; there will be pressure that will push your thumb off of the hose to allow air to escape. When air stops blowing out it is fairly near (TDC) on the compression stroke. Move on to STEP FOUR. Use a vacuum/pressure gauge. Hook up the gauge to your hose.
What was the timing mark on a triumph T140V?
However there was not enough slot in the ignition timing plate to get the pointer to point at the 38 degree mark. it was halway between TDC and 38 degrees. The engine was running great and when starting there was no kick back and it started then on the first or second kick when cold. It is almost like something is off a tooth.

When do you need to know top dead center ( TDC )?
Whenever you are doing a rebuild, building a new engine; or simply want to check and make sure the timing marks on your damper are still accurate. So, If you’re relatively new to engine work and have ever pulled, or need to pull, the distributor or damper from your engine; finding Top Dead Center (TDC) on piston #1 becomes an instant priority.
