Have an Excell 2500, VR2522...... Pull cord broke and now i think the spring is broke; where can I get a new spring and directions to reassemble the pull start?

Depending on the carburetor setup that pressure washer has, remove air filter, as well as plastic enclosure behind air filter. Remove bolts that hold carburetor to block. Remove gas line after clamping hose if has gas in tank. Remove throttle linkage carefully and spring. Once you have carburetor in hand, remove carburetor bowl. Look inside (where the bowl bolt goes into) and you should see a slot for a flathead screwdrivew, carefully remove that jet. Once that piece is out there should be a longer jet that falls out, if not, open carb and u will see other end inside carb, just gently press dwn on it to assist ot out. With a dental pick or simmilar tool, make sure all those tiny holes are open and clean of debri. Reassemble, and should fire up and stay running, if not amazon sells carburetors for between 5 and 20 bucks. Also if your carb doesnt have the center jet flathead screw to pullout, take whatever works and send it thru the center hole to open up that small passage..if all else fails spend the 6 bucks and buy a new carburetor..if any issues reachout on here again.
Cheers

You dont need to take it apart, simply wind up the tension and feed the new cord through both holes, tie the knot and release tension to rewind new cord

Anon, The wheel is probably held on by a push nut/cap. The easy way to remove is to cut through the cap retainer with a dremel tool part way and pry off with screw driver, these caps are not normally reusable after removal, check hardware store for replacement.
Check the attached links,instruction and guides, Good luck

Is the garden hose connected and turned on?If so make sure that the trigger on the gun is being pulled while your trying to start the engine! The backed up pressure in the high pressure hose can mimic a blown or seized engine in this situation.

your spring may be broke or might just have to rewind it they could be a pain somtimes

I like http://www.ppe-pressure-washer-parts.com/excell-vr2522-replacement-parts-pump See pump upgrade and compare to rebuilding. Another good site is www.pressure-washer-parts.com. Piston seals usual begin by overheating from excessive idling. You might add a thermostatic relief valve to help this.

Did you check the hose that goes into the resevoir.

should be a honda gcv 160 5,5 horsepower engine.

do a search for honda engine carburretor adjustment, plenty of pages on the internet detailing how to adjust carbs, mixture etc.

Leaving the engine running for more than two minutes without releasing pressure trigger causes aluminum pump to overheat and causing damage to the purmp, resulting in sudden low pressure. (see page 9 in manual)

Sounds like the diaphragm in the pump unit has failed, the engine and the pump are two seperate things the engine only operates the pump but if the diaphragm is leaking or broken you wont get any pressure
