Hi, Eddie throttle cable adjustment is fairly simple but before making any adjustments you should disassemble the throttle control housing allowing access to the inner cable for lubrication. I highly recommend "DRY SLIDE" then reassemble the throttle control housing and proceed as follows:
1. Back off the jam nuts on the pull and return cable.
2. Screw the cable adjusters all the way in.
3. Back out the pull cable adjuster enough to open the butterfly plate to maximum horizontal position ie. straight across.
4. Back out the pull cable adjuster until the carburetor piston or slide is all the way up.
5. Lock down the pull cable jam nut.
6. Back out the return/idle cable adjuster until there is 1/8th" free play on the throttle grip while pulling moderately on the return cable.
7. Lock down the return/idle cable jam nut.
8. Snap the throttle several times to ensure integrity.
9. If the bike rpm's are too low and the engine does not idle, adjust throttle stop screw as required.

The throttle plate is spring loaded to pull wide open, opposed by the governor which will pull the throttle closer to closed when the limited or specified rpms are reached. If the governor arm does is not connected to the throttle bell crank(linkage broken, off, or missing), it can't pull the throttle closed. If the arm does not move to close the throttle, the governor is likely broken inside the crankcase. or needs adjustment. The internals are a spool that moves based on rpm, pulled up by flyweights that has the external governor arm shaft 'trapped' in between the spool 'ends'. The spool will move the shaft and in turning, move the arm to pull the throttle closed. You adjust the arm on the shaft so the governor can pull the throttle completely closed with all the slack taken up.
I would check the throttle adjustment screw on the throttle assembly on handle bars. Be sure it is not screwed all the way in for max throttle. You can also check the carb and be sure that the idle screw is not adjusted for high idle as well. There may be an adjustment screw on carb for the cable stop.
Your engine produces max horsepower at 3600 rpm. The engine throttle should be set to max before you pull trigger. Pressure washes generally do not have automatic throttle. You do not have to use max power, but enough power to keep the engine running when trigger is pulled. You washer will actually last longer if you only use about 75% of rated capacity. Good luck
I suggest taking the handle apart to see if anthing is blocking the action of the trigger from inside, like some debris. Then see if the throttle cable moves if you pull it. If necessary keep tracking it back to the carburetor, maybe there is a piece of debris in there blocking the throttle lever on the carburetor.
The choke system is connected to the half throttle position, if you lift the throttle trigger the choke pull will automatically return, whilst trying to start do not lift the throttle trigger, the starting procedure is, pump the primer bulb as many times as it takes to 3/4 fill the bulb, pull the choke pull fully out, this will switch the saw on and engage the half throttle, crank the engine until it fires once, do not continue to pull,it will actually not run on full choke, if you do continue to crank with the choke fully out, you will very quickly flood the engine, now push the choke fully in, now crank the engine until it fires up, lift the throttle trigger once, this will dissengage the half throttle, and it should now come down to idle.
Pull starting a machine of any kind is fairly simple.
make sure your ignition is in the on position and that all safety switches are set (brake, oil level, blades, neutral etc.)
-give the engine extra fuel by the throttle position just past full throttle called "choke"
-pull the engine through slowly until you feel resistance
-let the rope back into the engine
-pull quickly on the rope (if the engine does not start on the first pull repeat the previous two steps )
Once the engine starts back the throttle down out of "choke mode"
remove 2 screws from right handle bar switch open it up and remove the cables from the throttle sleave. to remove from housing move in a circuler motion while pulling them from housing they will pull out as long as you pull them straight. then remove air cleaner cover and backing plate you will see where the cables hook to throttle bodies unhook cables and remove from holder noteing the one with the spring. tie a string to the end of the 2 cables anf pull them through the top, then tie the string on the new cables and pull them back through and re install everything and adjust the cables to 3/8 play in the throttle and done.
The choke is supossed to be closed when you lift thr throttle all the way up it it doesnt close all the loosen the cable I beleive its 5/16 make sure your throttle is all the way up loosen the throttle and pull on the cable you will see the choke plate close then tighten the throttle back up when you pull the thottle up all the the plate should close
