Getting a Spark but your Outboard Motor will not Start?

This vintage Evinrude Johnson 35hp has a good spark but will not start. Purging the bad gas to get it running again.

Thanks for the video Matt. People are sooo negative these days. Everyone seems to be a pro, watch 3 seconds of the video and pretend they know everything. I bet a lot of people found value in your vid. Cheers from AB, Canada

Thank you sir, you kept me from tearing it apart searching for problems. After draining the gas she still didn’t want to go but the starting fluid gave her the right motivation.

Nice video. I’m most impressed that you didn’t drop half your tools or parts in the water. I would not have been that skilled. 😂

After 5+ videos, yours helped me get my boat running💯

Thanks for the great video. You zero in on the issue way faster than I did. Smart man. Have a great day.

As as soon as you see the float bowl is empty, even while your squeezing the primer bulb, that tells you that the needle and seat is stuck shut…

Wayyyy too much starting fluid, if you must use it to see if motor fires up do one to two sprays in the carb and that’s it, more will only cause problems and not help the situation. Use premix gas to spray in a bottle or stop and try something else: in this case i would have taken the carb out and give it a good clean including the tiny little jets with a small clean wire and then carb cleaner spray or low air pressure to blow, then I would make sure idle adjustment in carb or 1 1/2 turn out from tight position (note: one 180 degree turn is a half turn, so twice of that makes a whole turn) but since your motor was sneezing sounds like it was too far turned inward, if it was smoking a lot and shaking a lot it would have been too far turned outward.

Thank you so much this saved me so much money!!

Try not to use starting fluid on a two stroke, you get no lubrication. Use a small bottle of premixed fuel

I same motor you need to get you a microphone or put your cowling on but what I can see is good the vocals sux when running the motor over all I would like to see more with out motor running

It’s a lean sneeze. Carbs are dirty and/or you are using bad gas.

Also try not to use starting fluid as it’s not good for the engine

I normally do a carburetor rebuild due to old gas or if not been used in six months and the float needs to be correct or fuel won’t allow fuel when the bowl drops Yeap mechanic by trade as well as automotive and aviation

Seems like the carb needs to be adjusted or cleaned. (The low idle issue)

Great video! I have the same problem! It will crank but it won’t fire! If I move the throttle 3/4 it will start! Need help!

[patriotproportioners]

I have a same problem on my mercury.. I wasn’t getting any spark then i figured it out and got spark and now it still isn’t starting

[TJFoley]

Having similar issue. Not sure it’s spark or fuel. How do you remove the air. Box I’m front of the carb?

[boredyoutuber]

I had no idea about carburetor cleaner could be bad for 2 strokes I learned somthing in the comments

[tmoney]

I have the same motor and mine would not idle but I could rev it up and it run fine but I started it and revved it up and it cut off I tried starting it again and would not start I sprayed starting fluid in it and it still won’t start it has spark but it won’t fire at all now please give me a tip I could really use one what would you try next if starting fluid don’t work and it has spark

[boredyoutuber]

Has anyone had the same problem from using too much oil or maybe the Rong 2 stroke oil? I used the other oil not marine 2 stroke and it doesn’t wanna start now I’ve used it before I’m wondering if I put to much or both rong oil and too much 😂
