Newbie 3rd Class questions:
Where can I buy a compression guage set? I am looking for the type with a hose and connector for the spark plug thread, and not the press-on type.
What is the correct procedure? Do you remove all the spark plugs or leave them in place and check the cylinders one at a time? Seems like it might make a difference whether or not the other cylinders were open vs closed up and compressing... Maybe it does not matter at all, I don't know...
DO you check compression by just turning over the engine with the starter?
What pressure range is acceptable for a 2000 Johnrude 175? I understand that they should be very close to the same pressures on all cylinders, but how far can it vary and still be acceptable?
Thanks in advance.
