    Force 85 really difficult to start

    I have done what you both said, and with the plugs in the timing was right, but WITH then out, it wasn’t right. I tried to adjust again but that didn’t help. One other thing I saw. Is when I have the choke on, the gas is coming out of the front, where the “filter” normally would be. Is that normal?

    Force 85 really difficult to start

    The plugs are all totally new, and they sparks. Yes there could be a chance of a leak somewhere, but I don’t think it’s the problem since it wouldn’t start at the beginning before the bang (but it could have happened before I bought it). I will buy the timing gun later, on my way home

    Force 85 really difficult to start

    I have now checked TDC, and it’s where it’s supposed to be. I mounted the carbs again after cleaning them. They were not bad at all, but to be sure. I also got some fresh gasoline, to be sure they weren’t anything wrong with that. It made to loud bangs again, so I think that I will buy a timing...

    Force 85 really difficult to start

    The starter works as I probably think it should, and I get a clearly good spark up to 10-12 mm, and I have just changed the spark plugs to be sure they wasn’t just old and tired. I think the next step is to buy a timing light gun, to check the timing is right. I began cleaning the carburetors...

    Force 85 really difficult to start

    Can it be because it has been transported in a trailer, laid down, so the gas in the carburetor ran into so it is drowned? I squeeze it until it is hard, and that's working fine. I have tried to start both with and without choke. how do I adjust the idle?

    Force 85 really difficult to start

    Nice to know what year it is. I think the fuel pump works as it should because the carburetor gets gas. When I hold a hand over the air intake, there comes a lot of gas out, so it is getting gas. Backfire... It made a loud bang yesterday, suddenly, which I suppose was because of a lot of gas in...

    Force 85 really difficult to start

    Hello everyone, im a new member in here, and also a beginner in boats. I have bought a 85 hp force (I don’t really know the year, but late 80’s I guess), which is incredibly difficult to get started. The previous owner had adjusted the timing and carburetors, but I’m not sure he have done it...
