Assembling the carbs, I noticed a float (383437) was hanging a big cockeyed and twisted the arm a little to align it. The foam split and the arm popped loose. Obviously a bad move on my part but it seemed to split more easily than it should have. I ordered two new ones–they are cheap on ebay–but am wondering: Is this common? Is there any adhesive that has worked to fix them? (If I had pinched the float firmly before twisting, it likely wouldn’t have failed.)
I also noticed that the Sierra needle/seat is dimensionally different than the original and the float would have been way out of adjustment without bending the arm.
Live and learn……
