Well, my buddy shows up at 7am this morning. I haven’t had my coffee yet. He said it died at every intersection the 35 mile trip unless he pushed in the clutch and mostly let it coast to a stop. Told him I’m not working on a hot engine so coffee it is. Went out about 30 minutes later and took the carburetor off. On the bench the tear down went as planned. Using a machinists metal ruler and feeler gauges I checked the surfaces for warping. Straight as they could possibly be. Checked the float setting and found the float drop to be 1/2 inch off. Completed the tear down finding no obvious problems. Carburetor cleaner and compressed air showed all passages were clear. Polished the power valve with 1500 grit wet sand paper and cleaned it. The accelerator pump was leather and I replaced it with the leather one from the kit he brought with him. Reassembled paying close attention to float settings and which metal balls went where. Flipped it upside down several times to make sure the float wasn’t sticking or hanging up. All good. Set the air mixture screw at 2 turns out from gentle seat. Reinstalled the carburetor checking the gasket to make sure the vacuum passage was unobstructed. Hooked up all the linkage and spring. Ten seconds of cranking and it fired right up. Idle settled down after the choke opened. Fine tuned the adjustments and off we went for a test drive. First stop I saw a smile come to his face as it came to a normal stop without dying. Thirty minutes and 12-15 stops and it appears the problem is solved. I’m calling it good.ðŸ›
