Morning everyone, this is my first crack at posting on this site!
I have a Johnson 2stroke 35hp J35PL3EEM motor and a few weeks back it started and idled normal for 30 seconds, but then stalled (has been running fine for about 2 months now). Ever since then I CANNOT get her started (cranks but doesn't fire up) no matter what ive tried. Below are my troubleshooting steps and some guesswork that im hoping some of you can help me out with. I DO have the motor service manual, which has been extremely helpful.
1. fuel line from tank started to get kinks in it so I replaced fuel line and both connectors. Bulb does get hard.
2. took each spark plug out separately and grounded to block and I do get a nice blue spark. Plugs did have black goo on the electrodes which I cleaned off
3. Tilted engine up to drain carbs, and manually opened flaps up and sprayed seafoam in each of them to try and clean it to see if I could get it started and still nothing. ALso have tried starting fluid but still no dice.
4. there is no killswitch key thing on my throttle, but ive been reading about this black/yellow wire that could cause me issues? Ive seen it and its not by itself, its with a bunch of other wires plugged in, should I try unplugging it?
5. doubtful its compression, but that's a guess, I haven't testing it
Seems like to me, the carbs are flooding everytime now and the next best guess is to order a rebuild kit and rebuild all 3 but I don't want to do that now, (in season), if I don't have to, since I don't have an easy way to get the boat on my trailer, dock is 3 miles away, and the marina doesn't have a ramp. In the fall I planned to do the carb rebuild.
What do you guys think? What else can I check? Every time I go back to thinking its ignition, I remember when I first had the issue and it started fine, but then stalled out like it lost fuel....... so im still guessing its something to do with fuel delivery.
