HELLO, l have a mercury 40 h.p. 1992 who doesn't run frequently. The last ride we done, every thing goes good, but the next day we want to go, it never start.<br />The gaz seem to be ok, and l have only a little spark on my plug, so l try to put a electric foam cleaner in my spark cable and l saw foam leaking in my rubber cap plug<br />I dont think the loss electric in my rubber cap is enough to make no trying start in my motor. Can you tell me what was my next step to test. thank you to help and sorry for my english because l speak french
