Hey all, I've got a 1978 55hp Johnson model 55el78s. This bad boy runs great at WOT but stalls when sitting at an idle. I have done carbs, checked fuel pump pressure. It will run with the throttle lever lifted up, but when the lever is put down it runs for a bit then stalls. There are no low speed adjustment. This motor runs perfect except for this minor problem, i just can't seem to narrow it down.
