My '93 200hp Evinrude pulls 120, 115, 115, 110, 110, 100. So there's more than a 15psi difference. Can I wait until the Fall to have the engine pulled apart or will that ruin my engine? Do I have any hope trying to just de-carb??
Do a decarb now, Zipp, then take new compression readings.<br /><br />My guess is that they will even out to an acceptable range.<br /><br />Moving to Evinrude troubles.
I agree. A decarb is in order. The manufacturer calls for no more than 15 lbs difference and youre very close. In fact if your heads are not matching and the first 3 numbers are from one side and the second 3 are from the other side, You may not have anything to worry about.<br /><br />If on each head the lowest number is the lowest cylinder, thats the way its supposed to be. The head chambers are slightly different top to bottom or "stggered".<br /><br />Good baseline -- recheck after the decarb job.
