1983 35 HP Evinrude Runs Rough
Posted: Tue Jul 31, 2018 3:27 pm
[The peak reading on a pressure gauge connected to the spark plug port on a dry cold cylinder of a 1983 Evinrude 35-HP and 35-year-old engine is 90-PSI] in both cylinders. I just checked the engine cold after it had been sitting for a few days.
Is [a reading of 90-PSI peak pressure] normal?
[The 35-year-old Evinrude 35-HP two-cylinder outboard engine] had been running rough. I was about to rebuild the carburetors, but now I am concerned that [the cause of the rough running] may be [due to] a bigger problem [than some unspecified problem in the carburetors].
