250 Optimax
I have read the thread in the FAQs and the doc in the Mercury service manual and still have a couple of "first-timer" questions.
1. What is the suggested way to "orient the throttle shutter to wide open" and maintain it there during the test?
2. Can anyone recommend a compression tester that will work for the Opti? The service manual recommends a Snap-On motorcycle compression tester that doesn't seem to be available any more. It's been replaced by a EEPV503 but $250 is a little steep for this shade-tree guy.
