Hi everyone! Hope I'm in the right place -- I've searched everywhere for an answer.
I've got an old (~1988) "Giant Vac" walk behind leaf blower with a Briggs 195422-0751-01 engine.
The problem: Doesn't run consistently at full throttle -- when it begins to die, it seems the only way to revive it is to close the choke and turn throttle nearly off. To expedite or reproduce the problem, angling the blower (or pushing up or down a hill) causes it to die within about 8 seconds. If you tilt it back and it starts to die, you can sometimes keep it running by setting it down flat again. What's strange to me is that depending on the rotations of the hi-speed (main jet) screw, it's sometimes able to keep running for 15-20 seconds at an angle.
What I've tried:
Replaced carburetor (and tried adjusting both hi-speed and idle screws on carb per instructions in owner's manual http://ift.tt/1y7M4ne )
Tried new gas
Small amount of SeaFoam in fuel
Visually inspected fuel filter (screen)
Replaced oil
My question: Am I just not getting the mixture settings right, or is there something else in particular that would cause it to run inconsistently, especially on a hill?
