Simoniz Power Washer

Hello! I am part of a Mechanics class in high school, and we're having this problem with a Gasoline-Powered Power Washer. Originally, the problem was a weak spring, so with that replaced, the throttle now works as it should. However now, the engine only starts when the choke is fully closed, with the throttle all the way in the backmost position. If, once you turn it on, you try and adjust the choke, the engine will die. If you increase the throttle, the engine does as it should. If you try and adjust the choke when the throttle is fully open, the engine will become extremely loud (almost unbearably loud). If you try and lower the throttle once you increase it, the engine will die. We have already tried taking the Carb apart, and it looks relatively new. The air filter is clean, and all the Gaskets are where they should be. Any ideas would be amazing. Thanks!

(if needed, I can post specs of the power washer, but it seems as if this is a general Small Engine issue)

 

Hello ChaseC, and welcome!

It would help to know what engine is on it. Who made the engine, model number, etc...
