I have a 1405, occasionally it goes thru a short phase where I can barely keep it running. I took it all apart cleaned everything very well. Downloaded the Manual set Float to 7/16 and 15/16. Set the others as well. It occurred again after 15-18 miles. limped it home running very bad. Plugs showed a weird burn pattern. the two on the the two on the middle on one side and the two on the outside outside were noticeably darker that the others. after investigating it turns out that one side of the carb feeds those, and the other side feed the others by design of the Intake manifold. I noticed when I pump the throttle the shots of fuel are normal, but at 1200-1500 rpm One side is dribbling gas at the ventury siphon, but the other is not. Is that Normal to dribble at higher RPM? I assumed if it were it would occur from both sides. So this is what I did. Opened again, Cleaned up real good again, blew air thru all ports and anything with a hole. Verified Floats were correct again. but not sure if the adjustment is from the corner of the float or a little past to the portion that gets flatter. I decided on the Flat portion to measure on. but a 7/16 bit clears a very little bit. hanging is almost exactly 15/16 on the bottom flat area by the corner. Then I swapped the Metering rods, plunger thing, and springs from one side to the other. It is still doing the same thing. Dribble ONLY when at higher to midrange RPM. Not during Idle. I assume it should all be atomized and no dribbles. Anyone seen only one side dribble? What did fix it?
