Procedure

1. Cut a piece of 1/2” plywood so it measures 10”x 30” as in Figure 1-5.
2. Fasten a six foot length of 1/2” O.D. clear plastic tubing to the plywood board as shown in Figure 1-5. Make a gradual rather than a sharp bend in the tube.
3. Inside the “U” formed by the tubing, measure off at least a 24” segment on the plywood board between the straight sides of the “U”. Divide the segment into one inch increments and mark these increments on the board. Start with the middle increment as zero and number in both directions.
4. Drill a 1/2” hole in the center of a rubber stopper the size to be a snug fit in the engine oil fill hole. Insert long end of tube thru stopper hole.
5. Add a shut-off valve or clamp in front of the stopper to prevent engine from drawing water into crankcase under cranking conditions.
6. Pour colored water into the tube until the level reaches the halfway (0) mark of the scale marked on the plywood board.

A starting problem could, for example, be attributed simply to an empty fuel tank. The chart below lists some common causes of engine troubles - use this as a guide to locate causing factors.
