    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Actually, I am at the end of the issues, one motor is completely rebuilt top to bottom. I am ironing out the kinks now. if I were to change the motors I would probably do one 200HP motor not 2. But after all this work I don't want to take that route yet. I understand these motors inside out...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Ok but my question stands should the reading with a voltmeter read say from a standing 12.5 battery go up right away or really slowly. When I read it with a voltmeter it went up slowly, I mean really slowly like 1 volt at a time it didn't jump up to 13 or so.

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Batteries are SuperStart Marine Deep Cycle. I almost always charge them before going out. I don't know if I did that when I took the picture. The motor was acting up so maybe I turned it a few 20 times and one went down a bit. When I did test it at idle it was really slow to gain voltage but...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Have a question on the stator, when I used the multimeter I noticed that the stator is charging differently that an alternator it is slow on building up the charge, at least on one engine it doesn't just jump up from 12.5 to 13.5 or so.The other one also is going upslowly but a bit faster than...

    Need to adjust the dial 1990 Force carbs mixture

    Not since I got the idle to work. I did take it before twice. But the wires were bad. Now the wires on the intake side are all good. Also the ignition is new as far as switch and kill switches and works properly. Waiting to take it out this weekend for carb mix setting as per Jerry 1 1/2 out in...

    Need to adjust the dial 1990 Force carbs mixture

    Ok I got news so fixing the wiring yesterday, plus new ignition switches and kill switches managed to get the system to work properly and the kill switches also function now. The engine that wasn't idling now has idle and runs ok but it has some hiccups or studdering while running. I made a...

    Need to adjust the dial 1990 Force carbs mixture

    Ok so one engine still starts regardless of kill switch plug in or not. That ignition shows ground on the yellow wire the other doesn't have it. I have to see if I unplugged anything at the motor in the morning. But the kill switches are new and opened when the lanyard is plugged in. I don't...

    Need to adjust the dial 1990 Force carbs mixture

    Ok got the new ignition switches and I tested them with a meter. So when the key is off there is continuity between the two M connectors on the switch. As soon as you turn the key the circuit opens and the kill switch becomes the one that controls the continuity. So I have to check if the switch...

    Need to adjust the dial 1990 Force carbs mixture

    I just found out thatvone 9f tye engines thatbI thought was adjusted and was ready to go had the idle adjustment bolt come loose and that's why it wasn't holding idle. I forgot to lock it up with the nut. Oh well at least thatbone is good. Working on the trigger wiring repairs on the other...

    Need to adjust the dial 1990 Force carbs mixture

    This is a diagram that I found it looks pretty close to my ignition except the blue wire that goes to M is black on mine.

    Need to adjust the dial 1990 Force carbs mixture

    Ok so the white wire that has the ground which goes to the junction box and connects to 2 black/yellows was connected to the ignition switch M see 1st picture. I am including the ignition switch diagram I wrote picture 2. The other ignition switch fell apart when I touched it so I have to...

    Need to adjust the dial 1990 Force carbs mixture

    Ok so the M in the picture has continuity with laynard attached. I should use the other 2 connectors right. Also I have ground without these kill switches connected so black and white wire at the dash disconnected. I have to check why I get ground and why the engine starts. The other engine also...

    Need to adjust the dial 1990 Force carbs mixture

    I took the boat to the lake and it wasn't pretty. I managed to adjust one of the engines idle and everything. The second one would not hold idle in gear. I have to mention I removed the kill switches on both on was not working at all. I bought 2 new ones and want to make sure I put them on...

    Need to adjust the dial 1990 Force carbs mixture

    Ok I just read the post again and noticed the adjustment is done in gear. I have not done that before. At idle when I turned the screw in I got almost to the end before noticing any stalling. But in gear it should be more obvious. I assume the 1 1/2 out and dialing it in to the stall position in...

    Need to adjust the dial 1990 Force carbs mixture

    Wow that's stupid. The only draw back that I rad about it in the reviews is the back light that is missing. Most are complaining about that. Didn't know about the battery.

    Need to adjust the dial 1990 Force carbs mixture

    Yeah I have seen that before thanks. Last time I tried to set this I had the issue with the trigger wires on cyl 1 of one of the 2 engines so I could not do it right. When I turned the screw out I did get the stalling but when I went the other way, I did not get the roughness until really close...

    Need to adjust the dial 1990 Force carbs mixture

    I want to take it to the lake this weekend and adjust the mixture and then the timing. I don't have the 90 book I do have the 92. So after adjusting all the components around the carbs, including timing at 28BTDC I have to adjust the carbs mixture and idle. Book says turn in all the way and turn...
