Oscillating Idle then stall under load. Please help!

Ok, let's solve this one. Remove the carb, and then remove the float bowl. Check the float bowl jet (which is the bowl screw) and make sure the jets both horizontal and vertical are clean and open. Tip the carb upside down and remove the float pin and float with needle attached. Look in the float needle passage and you should see the red float seat at the bottom of the passage. This is where the crotchet hook wood come in handy as you need to remove this seat. If you have no hook, but compressed air, you can blow through the fuel inlet and try to pop the seat out. Put your thumb over the passage to prevent the seat from flying who knows where. No air or hook try bending a stiff paper clip to dig the seat out.
With the seat out clean the passage way with carb cleaner. Now you must find a drive bit slightly smaller than the passage way, to be used to press in the new seat. Apply a very, very small amount of a very light lube to the new seat. 3-1 oil or lighter, to help seat it better. Carefully insert the new seat in the passage way with the rings on the seat down toward the carb body. Slowly and carefully force the seat down with the back end of the drill bit. Once it is seated, check to see that it did not flip and the rings are up. If everything looks correct, attach the new needle to the float and install with the float pin centered. It everything is correct, the float should seat level to the carb body, when looking at it upside down. If everything looks good reattach the float bowl, making sure that both the bowl gasket and the nut gasket seal properly. Reinstall on the engine and test unit. Remember to have patience and take your time. Good luck, but I don't think you'll need it.

Excellent! Thank you so much. I will do this tomorrow and let you know how it goes!
I can't believe it! Its fixed! You're a genius! Thanks you so much. You just saved me over $100 and 3 weeks of waiting for it to even get looked at. Here another video of it running properly. Thanks again!
Congratulations, I knew you could do it. Don't tell anyone else on this site as it will ruin my rep as a guy who's just a troublemaker and really only knows book knowledge and what he can find on the Internet. Sometimes I get lucky.
Carscw, that must be the first time you've seen me help some one solve a problem. I remember you telling everyone that I never help people solve their problems all the way through. Guess I should go out and celebrate tonight, or maybe I was right, just got lucky again. Yes, you can call me out on this as I'm picking on someone again.

P.S. are you available if I have problems with my Honda HRX:smile:
