Pressure washer takes oil in two places:
Pump oil is 20-30 weight SAE non detergent and comes half way up/ do not fill more than 1/2 way
Engine oil is 10W30 and comes half way up dip stick
IF you overfilled the oil >>> DO NOT turn power washer on it's side or upside down to drain oil >>> because engine oil will fill carburetor

When engine won't start
We pull off air filter so we have direct access to carburetor
Spray WD-40 into carburetor while starting
The engine will fire on the WD-40

You can keep spraying WD-40 into carburetor to keep engine running while moving choke to see if engine will run on it's own
Squeeze gun trigger so water comes out gun and pump pressure doesn't stop engine

If engine will not fire on WD-40
Spark is suspect
Your spark plug gets power from ignition coil
If coil is bad you get no spark > and coil needs needs replacement
Take out spark plug, clean it with WD-40 and use a bit of sandpaper in the spark gap
Put spark wire back on plug
Touch threads of spark plug to metal part of engine > pull cord and look for sparking between spark plug and engine
If you do NOT have any sparking, then coil is bad
If you HAVE spark, then your spark plug needs cleaning or replacement

If engine fires on WD-40 but will not keep running
Then either fuel or carburetor are suspect
Loosen hex nut on fuel filter located below gas tank >> if fuel flows, then re-tighten hex
Next, pull off rubber hose connected to carburetor to see if fuel flows to carburetor
If fuel is flowing to carburetor, then the carburetor is suspect.
Small engine repair shop will have carburetor cleaners

Check exhaust
There is a screen over exhaust
Make sure it is clean of carbon build-up > Use WD-40

Change air filter

Try a lawnmower repair shop or use miliput to cover the welds clean & dry the tank blend it half and half roll it out flat then mould it around the whole of the tank over the join with about ten to fifteen mm spare both sides then mould & smooth it into place, it's fantastic stuff but make sure the tank is clean & dry & give the milliput plenty of time to dry if you do it right it will probably out last the pressure washer.

If you know where the crack is you can use JB weld to repair it.
