This is a problem with GC-160 and GC-190 engines on pressure washers,
tillers, etc. Once they get some hours on them and as things seat
in-wear in, they get to a point you can not pull the start cord. If you
remove the spark plug, the engine turns easily then the valves need
adjusted. The valves are set .005" to .006" off the seat. This allows
enough compression release but the engine runs. I find the valves need
adjusted every 25 hours, not the 100 hours Honda states.
It is possible the motor is seized or the pump component has jammed. The Honda Motor usually has an oil minder(wont start if low oil). So that being the case you may have a problem with the pump. If you are handy and have internet it is possible to download a parts/repair manual for the type of pump involved. Otherwise take it to a repair shop. Sometimes these pressure washers are more costly to fix as compared to a new one..
Make sure your oil level is correct and not overfull. If ok, pull the sparkplug out. Then, pull the starter rope to see if the engine spins freely. If it does, pull it 4-5 more times to clear the cylinder of oil or gas. Put the plug back in and try it again.
However, if the rope fails to pull freely, you either have a locked engine or pump. You will have to seperate the pump from the engine to determine which is locked up.
try to tap on the recoil cover to see if the rope returns,remove recoil cover if that doesnt work. What type engine and pump? The type of oil used in which the engine or the pump both should be listed in either the documentation you recieved at purchase or online.
hi take out the bolts holding the compleat pull starter remove unit pull the cord if it wont move something is jamming it inside if it is ok then the fault is with the motor //seized or washer remove washer pump if engine turns over /pump seized the fault is 1 of the three you have now found out wich 1 starter, motor or pump it will take too long to go over all 3 get back when you have got this far merlinv12
It may be your engine, but it may also be the water pressure. Try this: Hold the trigger down while pulling the recoil starter. This acts as an unloader for the pressure washer, and may allow the engine to turn over. There is also an oil level in the pump as well as the engine. Check both levels.
Just a thought, but I've been there. Best regards, W/D
