    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    I think it should be fine. I have used motors numerous times without fault since it’s been rebuilt. I could blow air in carb when it was right side up and the carb wouldn’t let me blow air in when it was upside down.

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    I rebuilt carb 2 month ago. It has been used 3-4 times per week since. I’ve probably got 50+ hours on motor since carb was built. Fuel is less than month old, mixed properly, used the same tank and bulb I always do. No air leaks to note.

    Spark plug wires are ok. I cleaned the spark plugs really well. They weren’t particularly fouled out at all, but I will try a new set of plugs just for good measure.

    Checked that one out already too! Replaced my fuel adapter, only thing left for me to do is unfortunately see if my carb is cracked 😱

    I checked spark and compression today, spark jumps 3/8 inch gap well and compression is 96/100. I have probably got 50 hours on this motor since I replaced that cam roller and it’s run great. I assume I’ve got it linked and synced properly.

    I put gas directly into the cylinders. It doesn’t fire. I do have a bunch of air coming out of the tell tail which I’ve never seen before.

    I’ve got 3 tanks and 2 hoses. I’ve rotated all of them and put fresh gas in

    I have a 1990 15 hp Johnson that has run beautifully most of the summer. We go out fishing Sunday and it started right up on the first pull like usual, runs great, idles beautifully. My buddy hadn’t actually seen my motor since I’d tuned it up, and I was bragging about how good it had been...

    Fuel line for pressure tank

    I bought my first 1959 golden jubilee last night! It came with a duel line pressure Tank. Thr runner hoses desperately need replaced. Are these fuel lines specialized or can I get any line at parts store?
