Reply To: 18 Evinrude compression.

[mike n]

i agree with labrador guy. i have a 58 18 that i got running last summer. i didnt check compression but did all work to get it fired up. it started but ran terrible for first few minutes. i wonder if reed valves were stuck from dried up fuel oil mix or stuck rings , which i guess could cause low compression when checking. mine cleared up after a few minutes of running and runs great now. even if you had trouble with the powerhead, it isnt too difficult to find another for that motor.
