    1991 Johnson 9.9 - 2 cycle pull start

    Yes, agree the purpose of "link & sync" is to speed up timing as you add fuel. They have to be together. In my case, they were way off restricting the throttle from opening in the start position. I have no idea how the timing got so far off, but it did. Getting the cam roller lined up with...

    1991 Johnson 9.9 - 2 cycle pull start

    OK, Last post on this thread. I did the "Link and Sync" thing and the motor is running better than it has in years. I had figured out that I wasn't getting enough fuel into the cylinders because the throttle wasn't opening at start. Turns out that to properly adjust the throttle on this...

    IT'S RUNNING! Thanks to all that offered advice during this journey. I adjusted the throttle linkage to allow the throttle to be opened slightly more. My motor doesn't allow the throttle to go beyond idle speed in neutral and you can't pull the rope in anything but neutral. I also adjusted...

    Yes, I thought it would be a simple matter of rebuilding the carb and it would be fine. I've now had the carb off 4 times, each time cleaning out all the orifices with carb cleaner. Obviously, I'm out of my depth. I don't see anything wrong. I did notice fuel in the lower air box like the...

    OK, The first time, it tried to fire but didn't. I tried a second time with the choke, squirted more fuel in cylinders and this time, it ran for a second or two. For a while, it would fire when I pulled, but eventually stopped firing again.

    OK, still won't start. I've always believed that if you have compression, spark and fuel, it should start. I have a couple of questions: 1. Is my compression (about 90 lbs per cylinder) good enough? I watched a YouTube today on a compression test of a similar engine and his was 120. 2. If...

    1991 Johnson 9.9 - 2 cycle pull start

    Got my wife the pump while I tried to start. Same result so I'm assuming that's it's not the fuel pump. Took the carb off and the bowl was full of fuel. The little tube that runs from the nozzle well had come off. The one in the carb kit from Sierra wasn't as tight a fit as the one that was...

    By the way, I love EdChris177 idea of eliminating the fuel pump by using gravity.

    Thanks. I bought a compression testers with the following results: Top cylinder - 88 Bottom cylinder - 95 Johnson doesn't publish what they should be, but I know they should be within 15% of each other and they are. I purchased a spark tester as well. It fit between the plug...

    1991 Johnson 9.9 - 2 cycle pull start

    OK, I've reinstalled the carb and starter assembly. Now the motor starts, runs about 5 to 10 seconds and stops. I've tried to push in the choke, leave it out half way, etc. I've also tried to adjust the low speed adjustment and that does seem to have an effect on how long it runs -- but it...

    1991 Johnson 9.9 Model J10REIR. I don't have a compression tester. It ran great after cranking the last time I started it. Would this indicate good compression? Should I invest in a compression tester? I have the plugs gap at .030 per the manual. Are you suggesting I open them up to test...

    1991 Johnson 9.9 - 2 cycle pull start

    Kill switch is good. Spark is good. I pulled the fuel line from the carb and fuel getting to carb. Tried to start -- no luck. I pulled the carb off again and there was no fuel in the bowl. I took apart and reassembled, hooked up the fuel line and primed. This time I had a couple of caps...

    Since the motor run great after it starts, I guess you are thinking it might be sticking. I'll put an OHM meter on it tomorrow and make sure it's functioning properly. Thanks.

    1991 Johnson 9.9 - 2 cycle pull start

    Engine set up for a year. Got it started on muffs and starter fluid. Took it to the lake and it took about 1 hr and a 1/2 to get it to crank -- finally had to use starter fluid. I ran the boat up and town the lake and the motor ran great. I brought it home and have rebuilt the carb. It...
