So Jerry,
Care to make a recommendation of a good compression tester? I have two, both cheapies, one with a rubber nipple on the end to jam into the spark plug hole, one with a 45 degree rubber nipple. Problem is, I can't get a decent reading on all cylinders because I just can't get past the exhaust manifold to get to the spark plug hole on a couple cylinders.
Seems like I've seen them with a rubber hose and an end you can thread into the spark plug hole. Would that come with different adapters or do you have to buy the one specific to your application?
