Most engine's Operators manual will say to thread in spark plug's by hand, however this can be a difficult as the spark plug holes are usually hard to access with your fingers.
I will walk you through how to make a tool for the job.
What you will need:
- Spark plug
- Garden Hose ( I used some with a internal diameter of 12mm as this holds a spark plug)
- A knife or scissors to cut the hose
Step 1: Step 1: Cutting the Hose
Cut your garden hose to the desired length 17 cm should be long enough
Step 2: Step 2: Insert Spark Plug
Insert the spark plug into one of the ends of the hose.
Step 3: Step 3: Thread in Spark Plug
Thread the spark plug into the spark plug hole trying not to cross thread it.
Step 4: Step 4: Tighten
One you have tighten the spark plug using the garden hose pull it off and use the correct size socket and wrench to tighten it
Step 5: Step 5: Removal of Spark Plug
To remove the spark plug simply do these step in reverse. First loosen the spark plug with the correct size socket and wrench, then apply the garden hose to the spark plug and thread the spark plug out.
