Johnson 40 hp oil injector did not work

[lakelandstamp]

I have a 1995 40 hp Johnson outboard. Last fall the engine sounded very bad. They said the top cylinder did not get any oil and therefore it needed a new head. I took the head off and it doesn't look bad. There is a little scorring but not much. I did a compression test and it read 120 in both cylinders. Now I want to torque the head back down but am not sure what the torque should be. Is it 20 lbs? The I am going to run it in the lake.<br />Also now I am concerned that the oil injection may fail or clog again. Is it ok to mix the oil in the gas (50:1) and still run with the oil injector running also?<br /><br />Thanks for your help in advance.<br /><br />lakelandstamp@netscape.net

Re: Johnson 40 hp oil injector did not work

lakeland,<br /><br />Whoever told you that the oil pump caused your top cylinder to score is a blockhead. The oil pump mixes the fuel/oil before it reaches the carburetors, it CANNOT discriminate between cylinders.<br /><br />Your problem is with the carburetor that feeds that cylinder. Unles you address that carb., it's going to only get worse.
