I have recently posted a thread asking how to bypass the VRO system in my recently purchased 120 Johnson but now I have spoken to the previous owner and got a little more info.
The problem started two years ago and he would be out fishing when all of a sudden it would have a total loss of power..he said everything felt like a fuel related issue and it seemed to flood out at times while on muffs.
This is what he had done to remedy the problem..but with no success.
1. Bought new VRO pump (said it was around $600)
2. Drained tank and cleaned out with Seafoam (was advised to do so)
3. Paid to have carbs rebuilt ($500)
4. Checked all fuel lines and filter for clogs or leaks (found none)
Problem still happened so he sold me the setup.
Now it's my turn to try and diagnose / fix this and need your help..I have limited knowledge of outboards still but with the help of this forum have been able to fix three this year..thanks to all
What I have done since getting this (besides installing new steering cable) is:
1. Checked compression (125 on all)
2. Checked spark with a bulb that goes between plug and wire (all have spark at least but not sure how to tell if it's good enough)
3. Found the throttle advance spring was corroded and not going forward when throttle was applied..lubed and got it working.
4. Ran on muffs..idles o.k. but when throttled up it seemed like it flooded or was sluggish and died.
One other note..right before selling it to me he found a wire that goes somewhere under the stator / flywheel and he said it was hardly connected...he fixed that and it seemed to run better on the muffs for him...not sure if that is related or has any meaning etc.
Thank you.
