I have searched this forum for some answers on proper compression testing techniques but I have found some inconsistencies or not enough information.
Would some please tell me if the following steps are the correct way to complete an accurate compression test on my NA50 Honda Express?
1. Have the throttle wide open with the choke off.
2. Complete test on a cool (or hot) engine (or it doesn't matter?)
3. Do I have to turn over the engine several times until the compression gauge reaches it's highest value or just turn it over once and use that value?
4. After turning the engine over, leave the gauge on for a few minutes to make sure that the pressure does not continue to drop over time. The compression gauge I am using does not "lock in" on one value, but will decrease if I start to remove it from the spark plug hole.
Please let me know if these statements are true or false or set me on the right path. Thank you for your knowledge and expertise.
