I picked up a nonrunning 1973 18hp evinrude cheap at auction after cleaning the carb, replacing the water pump changing the oil in the lower end, new spark plugs, replacing one ignition coil and the pickup coil resetting the points and changing the condensers I now have a running motor.
Only thing that doesn't seen right is it wants the low speed needle jet open between 3 and 4 turns to get rid of the coughing.
Compression is good at low 120's on both cylinders, timing on both cylinders falls with in the two marks when running as checked with a timing light.
I've sprayed evinrude engine tuner around all gaskets on the intake side with no change noticed.
As soon as I get the rest of the parts to convert it to electric start I'll take it to the lake for a real test.
Question Does it sound like maybe I should be replacing the crank seals?
Thanks Mike
