My understanding is you have a pulse type carburetor, there is no float adjustment or choke. The only adjustments that are made are the high speed mixture and low speed mixture screws, any off balance adjustment on both screws can set the carb into a no start condition. Has the throttle cable been adjusted ? Try re-setting the mixture screws to the fully closed position count the number of turns that it takes to go to the end, then divide by 2 and bring it to approximate center. Remember, when making the high speed mixture adjustment the engine should be HOT and throttle should be what the manual spec sheet says should be. On the low speed adjustment the engine should be WARM and turn the screws until you feel the engine is running good. Once thats done set the Idle speed.After you rebuilt it the first time you said it ran great, now it doesn't run at all which is quite strange, the parts should not have worn out that quickly. If you decide to tear it apart, don't use any drill bits or anything to poke into the jetting or any other orifice, that can damage the holes or the jetting diameter when you clean it, this can offset the carb completely. Make sure you put back the springs and diaphragm correctly ( it's happened to me ).
