Working on neighbors power washer to get it to run I took off & cleaned carborator? I think I have the linkages reversed to the throttle plate because it runs ok if I hold the throttle open. There is a lever from the governor with a couple of bends so it could be reversed. One wire linkage to it with bends to get out of the way of a spring on the other linkage. Also, the lever on the governor is attacned to another that could be flopped 180 degrees. So where can I get a picture that shows the 2 holes of throttle, 2 wire links one with a spring, 2 holes on the governor lever, that levers orientation, and the lever its attached to position forward or reverse. Karcher has changed to Honda, tech help said go look at one in store, 2 places they recommend don't sell Karcher any more. Tecumseh online has the owner manual but no details of this area. Any ideas where to get the info i need. Thanks
Well no matter which way you turn that little linkage rod it either pushes or pulls. the bends are put there to keep it from hanging up on other things such as springs. try reversing the rod .the holes are a matter of opening the throttle should be 2 or 3 holes on one side of flat plate of stem for throttle plate. put the rod in the one that when in full open pushes the butterfly all the way open on the throttle.. also go to jacks small engines .com and select the motor type and just look at the schematic of the carb. you'll have to sign as a member and all that hooey but it don't cost nothing. just follow directions is all.

Butch if carb was good and clean and linkages were re installed properly including governor, it is possible the throttle tab/lever (what linkage hooks to) is loose on the shaft that opens the throttle butter fly. Check the attached links,instruction and guides, Good luck

This really sounds like a carb problem, good to hear that you are taking the carb all the way off and soaking it, this is the best way to clean a carb. I don't think it would be the fuel pump, they either work or they don't. I would check the governer springs and linkages, if one of these is hung up on something it would cause the problems the you have identified. Also, when you re-install the carb make sure that you have all the gaskets installed, it is easy to forget one and that will cause the engine to **** air and make the whole engine run like ****.
You will find your information by looking for model number and code of engine. Look on the fan cover, valve cover engine block or tag directly on the engine itself. Example would be Honda model gx340 from starter of engine. Then check google or mfg. web site for manual showing governor linkage. Norhstar uses several brands of engines. Good luck
Sounds like old fuel has plugged up the carberator. It will need to be cleaned and or rebuilt. Small engines that see limited use are prone to carborator gumming so need more freuent servicing than ones that see constent usage. Try using a fuel stabizer and or only put enough gas in the tank for the job at hand and running the maching out of gas before putting it away.
I was mistaken in my thinking about how the pressure washer works. There is a by-pass valve that takes the load off the engine when you stop spraying. The engine actually runs at a constant RMP. When the spray is on, the by-pass valve closes and this increases the load on the engine. This is what I had been hearing as a "speeding-up" of the engine and was no longer hearing. Anyway, I took the un-loader apart and blew it out with some compressed air. It works fine now.
