Its a 1980 mercruiser 470. I've got the entire engine & outdrive serviced, oil & a/f changed, plugs changed, n?w solenoid & ignitor, the boat doesn't wanna start. Confirmed I've got spark on all four cylinder, battery charged & gas in tank. So here lies my next dilemma; like I mentioned on my other post, 1-4 cylinder got a pressure reading of 120-135 although I think #3 has 118, did it twice and we're consistent on both reading. It cranks well but it just don't wanna turn over. Sometimes the carb makes this air purge noise, but nothing. Sometimes it almost turn over then not. I may have poured too much oil, a little over the full line, so I might end up realeasing some tommorow.
When I changed the oil, it was a little dark but no signs of water nor it was milky. Not sure how to check if gas is getting fed, but it's wet when I look down the carb. What should be the ideal reading for these engines also? Might end up performing a leak down test this weekend but I still need to learn how to perform such task still.
