De Industrie 2VD5

Another important milestone achieved and more confidence that the engine will start running.

The 1st cylinder has compression.

1st video: crankshaft rotates properly when a valve is held open.

2nd video: piston springs back as a result of the compression with closed valves.

3rd video: clear pop can be heard when the piston is held in compression and a valve is opened.

N.B. the pushrods are not included for this test and the 2nd cylinder is not included in this story because it is still open, i.e. it does not build up compression because a breather hole in the cylinder head is still open.

First time running on one cylinder. RPM is way too high due to an unbalanced carburetor but that can be tuned.

Only running short period of time since cooling and lubrication is not yet in place
