Does anyone have a picture of how the spark plugs on an Optimax should look like?

Thank you.

Just pull the fuel rail off and they come out.

[kostas74]

I forgot to mention that when i did the compression test and put the spark plugs back in i started the engine and an alarm sounded .
On the smart craft it says that the horn doesn't work but the horn keep sounding all the time!
Does anyone know how can i fix this problem?

I just came upon this thread, and I see #6 as normal and #5 as rich and oil soaked thanks.

[kostas74]

Only #6 is like that,all the rest are the same.

[terry taylor]

What year is this motor, and how long have this set of plugs been in service? Some don,t like champion if those are,I,m not impressed with the yucky black coating on #5 of 5 . Are you running rich oil, cheap oil, I,d try a new set and monitor closely. This is my opinion only thanks.

[kostas74]

Thank you Terry for your reply.

Year is 2007, spark plugs are in service for about 30 hours (NGK), i never used other oil than Mercury,s DFI and the engine doesn't use too much .
Can anyone tell me what to do about the horn problem?

[kostas74]

Still no answer

DDT tester means nothing at all. It just says if the injector is opening like its supposed to but does not tell you if its stopped up. If you want to clean it the cheap way just pull the injector out and hook it to a 9 volt battery and spray some carb cleaner through both ends and blow it out with an air hose. If that somewhat fixes it the pull all of them send em to Brucato for a proper cleaning.

Your running leaner on the #6 cylinder than the #5 cylinder. The filter in the injector must be getting dirty. Pull the injectors and have them cleaned by brucato or hydro tec. They will test the injector before and after cleaning the injectors. They will pint out the results of each injector. So you can see how each injector come paired.

If I was setting the fuel up on your motor I would set it like the #6 plug. The #6 looks good to me and others are rich.... But to get the plugs the same you need to get the injectors cleaned.

[kostas74]

So i have to clean the injectors , i will do that.
What about the problem with the horn?
Thank you for your help.
