Check earlier in the thread, I'm using a newer auxiliary tank as the main tank which has very good, newer EFI fuel line hooked to it. Has a clear filter before the electric pump I swapped in that looks good and a new stock filter just before the carb.
I drained the tank of the old gas out of a drainplug in the tank, gas was old but fine enough to run my mower without problem and no discoloration. No sediment/crud came out and with the position of the drainplug n the bottom corner of the tank it would have been tough for it not to.
Probably worth the carb rebuild regardless.
With the short cutouts, it's almost like the engine is braking, not just coasting like you'd think it would if it was starving for gas. Honestly, it's over so quick, the fact that there's a touch of engine braking is the only clue it's happened. If it coasted, I'd probably not notice. Makes me think.electrical/ignition.
Alternator is putting out proper voltage in garage at idle. I ran new power to the HEI/choke and that's hooked who well. Someone on another forum said they had a similar issue that turned out to be a slightly loose connector on the ignition switch, which would make sense. I had been under there for various things. Checked and it did seem like the small connector was loose a bit. Raining this morning or I'd be driving it for more "testing".
