At the lake yesterday and took off from the ramp when it felt and sounded like I lost one of the three cyclinders. No power, but idle sounds fine. Then I got an audible alarm from the consule. Got it home last night, checked and replaced all plugs, and varified that they were firing which they were. ( very well I might add, ouch!!!) Anyways, I am lost and can not figure out why it is still doing the same thing today.
