did a search and found some info but nothing totally similar.
Story goes engine ran perfectly (did 80nm 2 days before the incdent), this day 20mile out from home started to run like a dog, shaking and stumbling (like a bad miss). Would all of a sudden clear itself run ok for about 20 seconds then rumble for another 10. Ended up keeping WOT and staggered home.
Noticed for some reason when trimming motor in or out, stumble would rectify but still come back. The voltage dropped from 14.6V down to 13.9V when trimming motor.
First thought was fuel but with trim issue maybe not???
Got me home (praise God) but now running rough even at idle.
Have given full service (was up for it anyway- new fuel filters, oil and sparks), dropped all fuel out of tanks, emptied carbie bowls.
Now when running at idle its rough as, can pull number 1 and 3 plugs and no change in running, pull 2 or 4 and she stalls. There is spark at all four plugs?
So the prime start is attached to 1 and 3, is there a chance some electro gizmo is limiting fuel to 1 and 3? Or is just gonna be clogged jets? Any clues?
