Title: Gx390 cutting out
Post by: davep on February 06, 2015, 04:47:06 pm

Got a pressure washer with a honda gx390 engine. It runs for 15 mins max then cuts out. Took low oil sensor off but still does it. Any ideas?

Fuel filter or tank vent first

run it without the cap if it works buy a new cap. The filter screws into the bottom of the tank and can be seen from the filler

Take the lid off  refit loosely (for H&S reasons)  allowing tank to vent  and run the machine.
Or remove lid and run machine whilst having a fAg. (non H&S  method).
If machine runs ok go to here http://www.ebay.co.uk/itm/METAL-FUEL-TANK-CAP-FITS-HONDA-ENGINE-GX270-GX240-GX390-/390348931785?pt=UK_Lawnmower_Parts_Accessories&hash=item5ae29c02c9

If not pull of fuel pipe and see if petrol leaks on floor…blow up the petrol pipe …does it now leak faster?

common problem. Get a new cap, or keep the fuel tank only half full.
