You may have been right on this, we removed the tank, emptied it and flushed it and blew it out. I replaced the fuel line as well. Never seen and obvious problem but it runs like a top for hours now. Thanks for all the help
I hooked it up with a pony tank and it ran it dry, no issues. I removed the main fuel tank and replaced the line. Honestly couldn't find what the issue was. I haven't had it for a long run since switching back to the main tank. I've also since set the valves but they weren't bad, right side...
Yep, covers off, everything I could get to washed up.
It's a Briggs and Stratton 407777 type number 0174-E1. Has overhead valves. Do you know the intake exhaust specs? are they set from TDC?
I have a 20hp Briggs on a craftsman LT1000 on that has an issue. Like clockwork it quits after 5-10 minutes of operation. Seems like it's starved for fuel but not sure.
Things I have checked and eliminated.
- Fuel tank vent
- Diodes in coil wires ( still quits after 10 mins with kill wires...
