We have been in business for 25+ years.
We have a Sears mower in the shop that has
a GX530 Vtwin.
We serviced this mower earlier this spring and
delivered back to the customer. It was running fine.
They mowed with the mower about 4 or 5 times and
then it started running like the choke was part way on.

We picked up the mower and thought the air cleaner might
be plugged - it was fine.

Checked valve - ok

Checked the plugs and they were sooty but ok, put new ones in.

We removed the carb and went thru it several times - no improvement.

Changed fuel pump - no improvement.

Ordered a new carb - same thing

No excessive blow by. If you pinch off the supply
line the engine will run as it should.

We are stumped. Hate to start tearing into the engine
without due cause.
ANY IDEAS are welcome.
Thanks olf20

Replace fuel lines and clean the fuel tank.
