HI, It sounds like it is just stuck on the keyway as these can be very tight. You need to force the pump of evenly on either side and should come of if patient.

Motorturns over hard with pullstarter on my gx340 pressurewasher


You have a nice setup, lots of power. The honda gx340 has a compression release built into the engine so it should be relatively easy to start. With the pressure pump under load however, it will be very hard to pull the rope. With water connected hold spray gun open so water is running out tip and pull rope to start (for easy start, remove tip from gun) . If it still feels very hard to pull rope while holding gun open, most likely problem with lubrication in pump or engine valves are not adjusted correctly preventing compression release. If you suspect problem, go to store where you purchased the unit or any store that sells gx340 and pull the rope to get a feel of what force is required to start engine and compare to yours. Good luck.

What type oil is used in the pump? Checked engine oil and it's full. The oil in the oump seems to be low


You should use what the pump manufacturer recommends. Typically a 30wt non-detergent (non foaming) oil. Do not over fill. If there is a sight glass half way is normal. Or if it has a dip stick follow the mark there.

Honda GX340 11 Hp ..Runs fine until it gets hot , Cuts off and


FIRST...check the engine oil level. Some Honda engines have an oil sensor that shuts off the spark if the oil is low. This would also explain it shutting down when it get hot. Check the manual to see how to tell if the oil level is correct. Also, the oil should be brown and transparent, not black. It may need changing. Post again if this doesn't help :-)
