I have no sneeze at idle, only when RPMs get over 1400. I did check compression when I got back and it was 135 both cylinders and plugs looked alike with tan electrode and slight wet on outer parts of plugs.
This motor is new to me even though its 37 yo. Just took it out for first time and it has a cough or sneeze what ever its called maybe backfire that occures at about 1400 - 1500 rpms and higher. It is fairly vialent..I am not leaking any fuel from engine fuel lines and the bulb pressure does...
Well finally found out if I increased pressure test to 13# , it would start pushing gear oil out the drive shaft seal. I guess the new water pump I installed was pulling it up. Anyway replaced drive shaft seals and no more gear oil. Thanks to everybody for your help.
I have owned outboards before, this is not normal. This is not a film it is thick like drive oil and in 2-3" globs. Wished I had money for New 4 stroke.
This is alot of oil, engine is running well.I don't think I put this much oil in the 4 gallons I mixed 50-1. This is not just a film, there are 2-3" blobs.
I have just bought 1984 16' Jon Boat with 1984 Evinrude 35 hp. i have the engine in test barrel. Before ever cranking it I replaced the water pump and gear oil (pennzoil 80-90W marine gear oil) after running it at no more than high idle for 10-15 min I will start getting a good bit of green...
