Hi,
I'm having a problem. I know a little about engines, but less about outboards. I was once a diesel marine mechanic, but that was more than 2 decades ago in the army on on landing craft and such. I really appreciate any help you guys can give me.
Engine:
1984 Johnson 70 hp
Background:
Recently replaced a bad rectifier and power core. It was running rough and wouldn't stay running in idle but I adjusted the butterflys on the carbs, synchronizing them with the cam, it it idles well now as long as I have the primer solenoid set to manual start. Last year I rebuilt the carbs. It ran ok till the power core went bad. I had screwed with the linkage last year when it went bad, which is why I had to realign the linkage. While troubleshooting the electrical problem I had removed the flywheel to check the stator. Since putting it back I ensured the engine is at TDC (top cylinder is TDC at the TDC mark). I have not checked the timing since I don't have a timing light and I'm not even sure what wire to connect it too. Although I think it would be the top cylinder wire from the coil to the spark plug. I also took apart the fuel primer solenoid two years ago when I was troubleshooting a fuel problem. I also rebuilt the fuel pump 2 years ago. It ran after I put it back together, although it has always run rough at idle since I bought it a few years ago.
Problem now:
The engine starts and runs fine as long as I have the fuel primer solenoid in the manual start position. As soon as I twist the little red handle to the normal position it picks up in RPM's for a couple secs and dies. If I throttle up, it will stay running for a bit, but eventually die.
What sould I do now? :^) and no cracks about float testing it! On the water is the only place I feel relaxed!
