Engine model number J40TLENM. For the first trip out this year, I was having problems getting the motor to start and run well. Unburned gas/oil mix was bubbling up out of the water from the exhaust. So I took it home and rebuilt both carbs with carb kits. Now, I can get it to run (barely), but it is still running way too rich. The amount of smoke is unbelieveable. The smoke is mostly whitish in color (I think). The low speed adjustment screws are adjusted to 1.5 turns out from lightly seated.
I've noticed that the primer bulb will not get hard when pumping it up, and I've looked through the carbs and seen fuel squirting in when I pump the primer bulb when I have the flame suppressor off. I've also noticed that when I push the key in to activate the primer solenoid I do not get a click. The red knob is in line with the solenoid, as shown in the attached picture, so I'm pretty sure it is in auto mode.
I'm thinking the primer solenoid is stuck open, or the needle valve will not close properly due to me not adjusting the float correctly when I reassembled. But, would fuel shoot in through the primer jet when I pump the bulb if the needle wasn't seating?
I did try disconnecting the battery to see if the primer solenoid would close, thinking maybe there was a short in the ignition switch keeping it open. This didn't work either.
Any ideas? I've got the bug, and the warm weather is getting here so I really want to get this problem licked.
