1992 Johnson 150hp TJ150GLENC
After rebuilding all 6 carbs and replacing the float bowls and seals I'm still having a problem with my motor having an intermittent cough/sneeze and sometimes it stalls when going very low at trolling speeds. It seems to happen more when it's warmed up and been running for a while. WOT the engine runs great.
There is good spark on all cylinders and compression is good. Fuel is new, and lines are in good shape. I'm really puzzled what could be causing the problem. Should I try new spark plugs? Perhaps going up a jet size in one of the low speed jets?
