...after running for a few minutes.
At first start, fires right up, run like a champ. After about 5 minutes at full throttle (much less if you clutch the mower deck in; lots of load) it begins to surge. It eventually gets to the point that it stalls. I can fire it right back up, no problem but it will surge bad and stall out again very quickly; maybe 30 seconds or less and often backfires when it does.
Since it runs fine at first, its making me think its less a carb problem and more a fuel delivery problem. Like maybe I have a pinched line or the liner inside the fuel line has collapsed somewhere and is blocking fuel flow. I was thinking about running new line from the tank all the way up.
This motor also has the plastic "pulse" fuel pump connected to one of the valve covers. I was gonna take the line off and see if it squirts when I roll the motor over. Is that a good test?
