It started fine at the end of last summer, now I can't get it to start unless I pull the button and start it at a much higher RPM. I tried adjusting the idle with the "idle adjust screw", the rubber screw that presses against the tower shaft. I broke the rubber screw and can't find a replacement, then I put in a regular metal screw and broke the tower shaft. I can't find any of the rubber screws in stock anywhere, is there a place to get those? And once I replace the tower shaft and screw how do I adjust the idle so I can get it started? Carb is clean, new gas. Thanks for your help.
