I'm ready to pull my hair out right now, so I'm taking a break. Hopefully someone here can help me think this darn sneeze issue out.
-new plug wires, plugs(gapped .030), new coil wire
-new fuel lines and connectors
-rebuilt fuel pump today
-drop tested cylinders....all are firing
I've been chasing down air leaks for the last few days. I put a clear hose from the fuel pump to carb and eventually stopped the air from getting into the system. The clear line is still attached to the system until I get everything worked out.
Today, I rebuilt the fuel pump and then had an issue of sediment bowl not filling fast enough as the motor idled. I could press the fuel bulb and fill the clear sediment bowl, but the fuel pump wasn't filling it on it's own. Took it apart a couple times and reassembled and then tightened all clamps again. Seems to be staying full now.
Motor is idling fairly well now, but when I throttled up(as far as the motor will let me while it's in neutral), I starts to sneeze(see video).
Carb has been cleaned this week. I replaced the base gasket and set the float (parallel with carb body). Needle and seat are clean and in great shape. All orifices cleaned with small wire and carb spray. I pulled the fixed high speed jets a few minutes ago just to be sure nothing clogged them. They were/are clean.
Motor was link and synced again.
What am I missing? Could the float level be wrong and slightly starving the motor of fuel when I throttle up?
This is so darn frustrating.
